I wouldn't Touch the T'bolt today if I had to buy it. WHEN it works, it's great BUT the battery life that lasts all of about an hour if you use it before you need to recharge it would be the killer for me. I bought my wife a Droid 3 and she goes over 2 days before needing a charge. I get charged up and just using it sparingly with everything off (4G/syncing/GPS/Bluetooth/etc...) I have to charge it before I go to lunch. Heaven help me if I have to use one of those services. I don't have 4G in my area but when I have traveled in 4G areas and tried to use it, that hour goes to about 20 minutes. Early reports on the Bionic say that even using 4G, it's having over a day of use before charging. It's every bit as fast as the T'bolt with a higher res screen, dual core processor and a larger internal storage. If I can convince them, I plan on getting them to swap my T'bolt for a Bionic or a D3.
So, in short, if you don't mind using your phone on the charger all the time or getting a massive battery and deforming your phone to be able to use it for a moderately reasonable amount of time, then it's a great phone. If you want a phone that lasts the way a $250 phone should, I would look elsewhere.
