I wouldn't get one just because of a cool case with a keyboard attachment...I would get one because I liked the product in and of itself.
You're gonna be spending about seven hundred bucks for a sixty dollar case.
I only say this because they're not for everyone, I have an aunt that after a week never used it again in favor of using her laptop instead.
I never said I was getting it for the keyboard/case -- it's just nice to know that is an option. Even with the case it would still be easily portable. I already have a tablet so I know what they're like, I want a bigger screen. The new one is supposed to be very fast with 4g and have better clarity than a 1080 TV screen due to the retinal display.
