Sorry to be the downer of the group...
I bought the D2 the morning it came out and two days later I dropped it outside taking a picture and it landed on blacktop and some pebbles and when I picked it up it was all scratched up and was chipped all over the place. The screen was fine (thank god for gorilla glass) but the silver edge was just totally ruined. And it didn't even fall that hard. Insurance doesn't cover cosmetics so I thought I was just totally screwed but luckily (or unluckily depending on how you look at it) there was even more damage done. There was ONE SINGLE pixel that was red all the time no matter what was on the screen. I know for a fact this dead pixel happened from when I dropped it. I took it back to the verizon store showed them the pixel and they replaced it. Phew! Dodged a bullet Neo style there! But seriously, I do recommend a case because if the worst should happen you do have to live with it because again insurance doesn't cover cosmetic damage.
Because of this I went through pretty much every D2 case out there (and there aren't that many to chose from honestly) but I highly HIGHLY recommend seidio's d2 case.

Here is a review I wrote about in the D2 cases forum:
"I finally received the seidio innocase and holster for the d2 and I have to say it is the best case for it. It's sleek, not too thin, not too thick, just perfect. It even has an opening for the noise reduction mic on the back which is something the other cases I've tried doesn't have. It has the soft touch feel so it feels really nice. It fits on the phone very snuggly too. It doesn't feel like it is too tight (like the Verizon case) or too loose (like the rocketfish case from best buy). I feel like if I drop the phone the case will not pop out (although I have not yet dropped it since I've gotten it) I highly recommend.
I also got the holster which is much better than the Verizon one. The phone can actually go in face in or face out and it has a clip to secure the phone in place and you push it up to remove the phone. I like this better than Verizon's holster because you would have to slide it out and it was very cumbersome to do because it is so tight. the clip is strategically placed so you still have access to the headphone jack and power button. It is a little harder to remove from the holster if it is faced out but not really a big deal.
So what are you waiting for? Order it now! Lol. Trust me; you won't regret it
