What is the main benefit of buying an ipad ? what can you actually do in 16, 32 0r 64 gb when you have 510 gb laptop with you ?

Here you can read all about the iPad; http://www.apple.com/ipad/

For me? the advantage of an ipad over a laptop....instant on, instant off, thin and portable. Check your e-mail and put it down, not wait 5 minutes to boot, check your mail, shut it down.

Is it as fully functional as a laptop? no. Not meant to be. What it lacks in functionality it makes up for in portability.

Is a necessity? no. But quite handy.

Touch screen.

Very portable, can bring to bed, toilet, aircraft seat and take instant pix, watch movie, email of course,

Great App. When come to detail graphic work or elaborate spreadsheet, a laptop is preferred.

Besides everything mentioned already? 8-10 hours of battery life with a device that weighs about 1.5 pounds (0.7 kG).

Haha toilet...... Classic

How about microwave?
