With an iPad reservation for launch day, I can't help but be curious about how durable the iPad will be. My analysis, based on other Apple devices: It's likely the aluminum back will get quite a few scratches if you lay the iPad down to type on it constantly. The glass covering the screen and the black bezel should be very scratch resilient as the iPhone is. The metal bezel around the screen could probably get marred easily. One drop should be enough to dent the aluminum or put a crack in the screen, either could make the iPad annoying to use. I used a flip style case for the first-generation iPhone, taking my iPhone in and out for extended use, which I liked. I used a sleeve for the iPhone 3G, and I wasn't a fan of taking my iPhone in and out of it for everything, and the inside is difficult to clean. I have a Seidio Innocase II on my iPhone 3GS and I like it, though I would prefer Apple to just make the iPhone more durable. The iPad is a gorgeous gadget without a doubt, but it's unlikely it will be particularly durable. Will you use a case? I'm torn between putting a full case over the back and metal bezel or just getting a sleeve/bag to protect it while traveling. If Apple's iPad case is available on launch day in the Apple Store, I will likely buy that and consider other options as they become available.
