I tried it. I don't want to sound like I'm knocking it, because I know they put a ton of work into it, and it's still in it's early stages... but I wasn't crazy about it. I ended up switching back to Das BAMF 1.7 after like 2 days. It wasn't as smooth as BAMF, and was a little laggy at times... I never got gps to work at all (although others say it works fine for them, so not sure what's up there)... and both 3G and 4G reception were worse, I had a tough time locking on to either, even though I was using the same radio as BAMF.
On the upside, you get some nice GB features without having to worry about your phone bricking, and netflix works.
I came from a Droid 1, and cyanogenmod on that was awesome.. by far the best rom that I used. So hopefully when it gets to beta and some kinks are worked out, I'll give it a try on my TB again.
