Yep, TB is very worth it. Once someone posts a complete "safe apps to freeze" list, there will literally be about 40 things to remove! My DX got pretty darn snappy after freezing all of that crap. TB is also great for saving app data. Let's say you have a game that you have leveled up on but get sick of playing. You can use TB to save exactly where you were and uninstall the app. A few months later if you want to reinstall and play that game, you can just grab it from the market and TB will put you right back where you were.
I agree TB is worth every penny, I like the fact that since they have been pulling apps off the market the wireless tether for one and the other a music app that i use frequently to download mp3s all I have to do is go into TB and restore the app and no worries
