I've been using the same Blackberry since 2009 and think I should give up waiting for Blackberry 10. I like my phones durable because I take them mountain biking and such. The 4/4s seemed pretty fragile due to the front to back glass that didn't sit flush. Now the 5 seems like a step in the right direction as far as durability is concerned. I'm just wondering though since it's not specified anywhere, did they use gorilla glass or what?
