I was really pleased with Cyanogen initially but found quite a few annoying bugs (mainly browser related) that have soured the experience somewhat... not having search functionality in the email client is painful :(
Not long until I get a One X and then I'll stick with Sense again I think, main reason for rooting was to try and make some more space with the Desire's pitiful internal memory allocation :p
Turns out I copied the 7.1 ROM onto my SD card already so I've just installed it and had a play around. Seems to be working 100% so far, and must say I'm loving it! it appears so slick and smooth, and the lock screen is awesome! So nice to have a quick way to stick the phone onto silent mode!
The browser is not an issue for me as I use Dolphin Browser HD. :)
Moving to Netbooks, PDA's and Phones.
