I'm loving it over 2.1, Its in beta so it's missing things that you could do and have on a 2.1 rom but final build has been released. I'm loving the speed increase, it might not seem like much but haveing a quick, responsive, snappy phone makes it so much more enjoyable. Java is great, I can easily go to a streaming video site, open it up, wait 5 minutes, and watch a movie or tv show with no problems, no downloading and putting it on my sd card. I also like chrome-to-phone, which might not seem like a big deal but save me some time alot when I have to run out or needing to pull a map or something up on my phone. Overall I think it's great have used 3 different versions and finally settle on Bugless 0.1 which im getting 20 linpacks on! More than I could on any 2.1 rom! I think once more things become available like themes and thing for 2.2 and the final build comes out more people will probably find it much more enjoyable.
2.2 is very enjoyable.I find myself using Flash 10.1 frequently and its a great addition.Apple really messed that up because Android will excel with that added feature.The Speed increase is great and i have to agree with what you said.But one question what is Chrome to PHone? lol
