iPad - Frequently Asked Questions Answered

iPad FAQ: Your top 14 questions answered

Article Summary:

Does my iPad have a hard drive?

Instead, it uses NAND-based memory to duplicate the functions of a spinning hard disk, which would suck up enough power to send battery miser Steve Jobs over the edge.

All your applications, videos, photographs, downloaded music, movies, television programs and other data goes into the flash memory.

Depending on how much money you decided to throw at Apple, your iPad has 16 GB, 32 GB or 64 GB of storage space.

Compared to a new Mac or PC, the iPad's storage is Lilliputian: The low-end MacBook Pro, for example, has a 160 GB hard drive, while the cheapest iMac sports 500 GB.

But it's in line with the capacity of its closest cousin, the dinky iPod Touch.

Can I print from the iPad?

No. Apple didn't stick a USB port in the tablet.

You'll have to shunt what you want to a print to a PC or Mac using e-mail, or sync the iPad using iTunes or MobileMe, then print from there.

I want to read some books. What do I do?

Apple's supposed to add its free iBook app to the App Store on Saturday.

Install it and you'll be able to purchase e-books from the limited stock - limited compared to Amazon.com's e-book inventory, at least - that Apple's put together for the launch.

Last week, Amazon announced it would rewrite its Kindle software - already available for the iPhone, as well as the Mac and PC - for the iPad.

On Friday, the Kindle iPad app became available.

And how does the iPad do as an e-reader?

We haven't put hands to one long enough to find out.

Can I watch movies, TV?

You can rent movies or purchase television episodes from iTunes, or if you're a Netflix member, download the free app to stream movies and TV shows to your iPad.
ABC has also posted viewing software (ABC Player) on the App Store, the only major television network to do so by late Thursday.

Can I do real work on my iPad?

Depends on how you define real (as opposed to fake work, which for us means a nap or ESPN), but you can write and crunch numbers and craft soul-sucking presentations if you buy the three apps that make up the iPad version of Apple's iWork suite.
Apple's used a way-back machine to return to the days of the unbundle, when suites weren't collections with a single price, but an agglomeration of separately-purchased programs that worked together, more or less.
In other words, you buy the three applications - Pages, Numbers and Keynote - separately from the App Store.
Of course, if you're a numbers person and wouldn't know a gerund from a gradated background, you pay for only what you want and the hell with the rest.

There's no camera on the iPad, so how do I get photos onto the thing?

Out of the box, the sync cable is your friend: Use it and iTunes to synchronize collections on your computer with the iPad.
By the way, you'll need to update your Mac or PC to iTunes 9.1 - Apple slipped that out Tuesday - to sync with the iPad and organize the books you buy with the iBook app.
If there's $29 burning a hole in your pocket, you can spring for the iPad Camera Connection Kit.
One of the two adapters accepts a camera's SD memory card; the other links your camera's USB cable with the iPad.
Too bad the kit doesn't ship until later this month.

I tried the on-glass keyboard and hate it.

The iPad also syncs with Bluetooth keyboards, so if you have one of those, you should be able to link and use it without any trouble.
Apple sells a combination keyboard and iPad dock - called, not surprisingly, the iPad Keyboard Dock - that also includes an audio jack for connecting the iPad to speakers or a stereo system.
While some reviewers have received a dock, Apple's not shipping to the rest of us until late this month.
An Apple-branded Bluetooth keyboard - basically, the same keyboard as in the dock - also costs $69 and is available now.

I have a MobileMe account. Can I add the iPad to the list of my devices to sync?

To MobileMe, Apple's sync and storage service, the iPad is just another device.
You can sync the mail, contacts and calendar on the iPad with your iPhone, Mac or PC; use MobileMe's 20GB iDisk to store documents, like those you create with the iWork apps; register with the Find My iPad feature; and remotely wipe a lost or stolen tablet.
If you don't have a MobileMe account, you can try the service for 60 days free of charge.

Ten quick Calculator tricks on a Mac

Ten quick Calculator tricks

by Sharon Zardetto, Macworld.com

Here's how to get the most out of Apple's built-in tool

The lowly Calculator sits there in your Applications folder. It’s so unassuming you barely notice that it has menus and little interface details that make it not quite so lowly after all. These tips work for the Basic calculator. Many also work for the Scientific and Programmer versions available through the Calculator’s View menu.

1. Copy and paste numbers

Need to include a quick calculation in an e-mail message? Because you can’t select anything in the Calculator display, it’s easy to forget you can still use Copy and Paste commands with it. The Copy command (Command-C or Edit -> Copy) always grabs the currently displayed number and places it on the Clipboard so you can use it elsewhere. And, if you’ve copied a number from someplace else, just use Paste (Command-V or Edit -> Paste) when the Calculator’s open to insert the number in the Calculator field. (Many OS versions ago, you could paste in a calculation like 17*34, and it would appear in Calculator as if you had clicked those keys; now that calculation pastes in as the number 1734.)

2. Pick your precision

If kiwis are selling 3 for $5, does one of them cost $1.66667? When you don’t need 15-decimal place precision, use the View menu’s Decimal Places submenu to specify how many digits you want displayed. The displayed number is rounded, not truncated, so 1.66667 becomes 1.67. The actual number is stored internally, however, so you can continue with a calculation that uses the true number instead of the rounded one.

3. Convert units of measure

You may never have to convert hectares to acres, or inches of mercury to pounds per square inch, but the Convert menu provides more mundane changes, too. For example, use it to convert metric units to any of the stubbornly held standard measurements the U.S. uses. Enter a number (or work with the one already there from a calculation) and then choose a category from the menu—Length, for example. Use the pop-up menus in the sheet that appears to specify what you’re converting to and from. The Calculator displays the answer in the chosen units.

4. Repeat the last calculation

With the Calculator’s hidden “repeat the last operation” function, it’s a cinch to compute something like short-term compound interest. Start with 1200 dollars times 1.06 for the first year’s 6 percent return and you get 1272. Just hit Return again, and the number is multiplied by 1.06 again; another press of Return gives you the third-year total of 1429.22.

Alternatively, you can enter numbers in between the repeated operation. So, after the first calculation is done, you can enter 1500 and press Return to get that number multiplied by 1.06.

5. Use the paper tape

The paper tape window not only serves as a quick reference, it can also be printed or saved. This shows the result of the special “repeat last” function, which uses repeated clicks of the equal sign (=) key to perform the same operation—*1.06 was entered only once.

The Window -> Show Paper Tape command opens a small window that shows each of your calculations as soon as you press Return or click on the equal sign (=) key. This lets you check for incorrectly entered numbers. If you realize you want to see your history only after the fact, no problem: Any time you open the paper tape, you’ll see everything you’ve done since you opened the Calculator for the current number-crunching session. If you need a copy of the paper tape, choose File -> Save Tape As or File -> Print Tape. You can also select any part of its display and copy out the information.

6. Store a number

You’re figuring out the cost of tiling the kitchen, with and without the pantry closet, and maybe the back hallway, too. You don’t have to re-enter the $6.47-per-square-foot cost of the tile for the three different calculations.

Enter 6.47 and press M+ to put it into memory. Then, calculate the cost of each area’s tile by multiplying the square footage by the stored tile price, retrieved with a press of the Memory Recall (MR) button. Enter 14*16*MR for one cost, 6*7*MR for the next, and 2.5*3.5*MR for the last.

7. Delete a digit

If you type or click the wrong number, there’s no need to clear everything by clicking on Calculator’s C (for “clear”) key or pressing C on your keyboard. (If you have a full Apple keyboard, you can also use the key labeled Clear.) Press Delete on your keyboard to erase the last digit you entered; press it multiple times to continue erasing digits. (The Forward Delete key doesn’t work for this.)

8. Quickly switch calculators

Click on the Calculator’s Zoom button (the green one of the three buttons in the upper left of its window) to cycle through the three kinds of calculators—Basic, Scientific, and Programmer—instead of using the commands in the View menu.

Normal Calculator

9. Easily change a mistake

If you enter the wrong operator by mistake—pressing the plus sign (+), say, instead of the minus sign (-)—just press the correct one next. Calculator will ignore the first operator.

10. Specify a negative number

Normally, you can’t calculate 4 multiplied by negative 5, because 4*-5 is assumed to be a typo and is treated as 4-5. But you can reverse the “negativity” of a number you just entered by clicking on the Calculator’s plus-or-minus key. (It’s the key with a plus sign on top of a minus sign. You'll find it to the right of the C key.) So, press 4*5 and then, while the 5 is displayed, click on the plus-or-minus key to make it negative. Press Return to see the answer: -20.
