Hi guys, I've just tested this on my archos 101 and it does seem to work. Pretty good timing as I was seriously considering swapping it for the advent vega. I've installed as instructed, installed titanium backup and it seems to be working fine for freezing apps (archos widget etc), though uninstalling some of the crap that comes with it (news and weather, system monitor) works, but after a reboot it's back again - I assume this is due to the read only nature of the android partition (just guessing here!). I'm going to try root explorer shortly and see what effect deleting things has - if it works at all.
There doesn't seem to be any malicious effects so far, although I doubt I'd notice so early on anyway
I've taken a screenshot with my x10 as taking a system screenshot wouldn't really prove anything.
