Well, if you're interested in purchasing and are coming from a smaller phone. Check this thing out in the store. It is a little bit of an adjustment for me. But without a physical keyboard I am glad it is bigger. The screen is muuuch better than my OG Droid. LTE is nothing short of a miracle and surprises me every time I use the speed test. Browsing the internet is completely natural on the Thunderbolt. I can say with a straight face I can use it as easily as a desktop browser. It is just so quick and fluid and I feel like I can get stuff done. That being said, I do not see the need for a dual core at this point. Yes, the single core will be outdated by summer, but the dual core will be outdated by fall with quads. The processing power of the TB is completely fine for current games and most needs. I personally like the kickstand. I think it is kind of silly but in the same respect, it's awesome for videos and I'm sure for video chat. Battery life sucks. You're going to need to spend more money on either extra chargers or extra batteries. But it's hard not to find a phone that has a 4.3" screen, Lte, lots of background features in Sense and be completely feature packed and get good battery life. And my favorite part of the phone has to be the ability to stream whatever I want whenever I want without the worry of overages. Now that carriers are switching to tiered pricing, the Unlimited Lte for the same price as unlimted 3G is something else. I showed my boss today who has the incredible a speed test, and he said he wasnt sure if he'd make it till summer to see the iPhone 5. We'll see. Simply put, crazy fast phone with ability to do 95% of things on the market, great media device but be prepared for less than stellar battery life.
Also, I think there are threads already set up for this kind of question. just an FYI
