I've cooked several roms with this already. After using 2.5 for a month or so I guess I've gotten used to what some claim is its' slowness. As for 2.1 it is snappy. Looks like it has a flip issue, but not from tab to tab, only when going from the winmo interface back to Sense.
So far, some of the 2.1 mods will work, transparent top and bottom curtians, but compact home messes it up good. Clock seems smaller,
