I'm up for an upgrade in February, and frankly, the HTC Thunderbolt has stood out to me since release. Most of the other higher end devices are too expensive, and I'm not willing to throw down that kind of loot for a phone anymore. I purchased the D2 when it was $299, and it's been the worst phone I've ever used. That said, what do you think of your Thunderbolt? Developing? Durability?
