Hi there! I've had my White 64GB iPad 2 since March 11th, 2011. I have used it with 5 different cases. The best ones I have used have been the BookBook case by Twelvesouth, the Belkin Access Folio, and of course, Apple's Red and Green Smart Covers. I have probably dropped my iPad once or twice, that's it, and it's either been in a protective case, or fallen on carpet, therefore leading to no damage. My iPad has not one scratch on it, except for a mark made by the zipper of a case. recently, I've just been using the iPad with the Smart Cover and that's it. This is been mostly just around the house, though. I'm flying to New York City in the next few days, which has lead me to the question of if I really need to use a case when I take it. The iPad works way better without one. I've bought an Incase Sling Sleeve to carry the iPad in. My only concern is that it could be damaged while I'm transporting. I wanted to make my decision based on what others have done. My question for you is how do you use your iPad? With or without a case? Your thoughts? Thanks!
