CyanogenMod's Nightly's 7 has now launched a Release Candidate for Gingerbread 2.3.2 Very smooth. No hiccups for me. Rotary lock screen and a few other goodies. The only thing I would recommend to anyone new switching to CM7 or, indeed, from 6.1 to CM7, is that a full wipe of both phone and SD card is needed and to reinstall (not restore) everything afresh from the ground up, as if it were a new phone. This only needs to be done once to avoid any conflicts and is well worth the trouble initially.
