I would have waited. You still have 2 weeks to see if you can stand the battery life on this bad boy. It stinks, for sure, but I find it bare able.
Love Moto Blur, or hate it, the Bionic tops the TB. It has an HDMI output and dual core, and with a bigger battery it will have ore sensible battery life and maybe you can leave it on 4g all day without sweating it out. There is the Vigor coming out, which ought to be sweet. Also, the iPhone 4s/5 is coming out this month. The only thing I am disappointed that I didn't wait for was whatever Galaxy S phone that Samsung puts out for Verizon. I liked the Charge, and would have bought it if it wasn't so terribly speced. The display was great, and supposedly the battery life is improved too. If the rumors are true, the October phone from Samsung will be the Galaxy Prime, with Ice Cream Sandwich. We'll see.
But if youre set on the TB, then congrats, and welcome to the family! There are plenty of ROMs to flash, so get rooted and flash away!
