I think they are stable enough, but after spending a couple hundred dollars (see above), I'd hate to
drop it or get it too scratched.
Well, I've dropped mine a couple of times with no ill effects. You can't
play frisbee with it, but it's not a delicate piece of china either!
As for scratches - I never understood the fascination and obsession over scratches on
portable electronics. Neither my iPhone or iPad are in a case - since it takes away, for me, one of their greatest advantages - their size (mainly the thinness). When I quizz my friends about the reason they obsess over scratches they cite resell value - forget that! If I decide to sell my device, they can take it in the condition its in. If someone buying a used device scratch free they can
track down one of the overly obsessive or go get a new one. I bought my
portable devices to use and I don't mind if they get scratched in the least.
Indeed, I love my
ZaggMate case because it protects the front and doesn't increase the
thickness of the iPad that much, while providing a nice real physical keyboard for more intense editing sessions (with two
shift keys!). The back of my iPad has gotten scratched up more - if I really was concerned about it I could have put a
clear protector on - discount and dollar stores have lots to choose from that are cheap, and of course vendors like Zagg sell them too.
On a related note, I am impressed with the iPhone 4 - in a year of hard use all I have to show for it are two minor scratches on the back, one on the front and a small (small head of pin size) chunk from the bottom near the band where I dropped it out of my car onto a rock. It lives in my jeans pocket and I try to remember to keep metal and other hard objects out of my pocket but I occasionally forget - it handles it all well. My iPad and iPhone 3GS are covered in far more scratches on the back and the iPad has a few dimples in the back (!!) where the soft aluminum deformed. I don't expect them to make the back of a future iPad out of gorilla glass due to weight issues, but I wouldn't mind it from a durability standpoint. The iPhone 4 is a tank!
