Thunderbolt, which replaced my Droid Incredible, which replaced my original Droid.
I'm glad to be done with the Thunderbolt. I love the screen, I love the kickstand, the battery life is good but this is my third Thunderbolt as the prior two had hardware issues. I'm on edge every day waiting for the Thunderbolt hardware to fail. November 10th can't come soon enough.
Not 100% sure I'm switching (depends on what off-contract prices are). But if I do, I'll be coming from the iPhone 4. I've had 3 Android devices prior to the iPhone, and I love the vanilla-ness idea of the Nexus.
Bionic, especially after the unsellable note issued by VZW. The problem must be a very major one that warrants pulling out all unsold phone from stores. As a Premier Silver Reward Zone member at BB, I have 45 days to return/exchange phones without the restock fee.
