yes.

energyrom is a very popular one. i have had issues with it myself but alot of people love it.

i use the nfsfan rom. runs 6.5 on sense 2.5 and has great battery for me and is very stable.

for android look for gen.y dualboot and that'll get the dual boot going for you. there is no true dualboot as we need winmo for a few things in android still. feel free to check out the android thread.
