I run helmi's WM6.1 on my ppc 6700 (in new zealand) and it is amazing, faster than WM5 and the A2DP for bluetooth actually works!!!! and almost flawlessly :P i did upgrade in june and have been using it since then. Even watched a movie on it last night.
Anyway you do get short of space, just install only essentials onto NTFS and ur fine, everything on storage card is way to go my friend.
Lennysh stuff is good, i really need to donate to these guys, but not until christmas time
no money until i stop studying and get a summer job.
Go with lennysh i use his cube and its good (and free)!
