Hello, i have become very interested in xbmc and have decided to get myself an acer Revo r3700 as a late xmas present. i want to 1. stream tv shows and movies (that i own) from my NAS via xbmc 2. watch freeview via catchup tv on xbmc 3. watch iplayer via xbmc 4. watch skygo/skyplayer via internet browser. i see ebuyer has 4 flavours of revo varying in OS and RAM. prices go from £200-290. basically 2gb or 4gb of Ram and a choice of win7 and Linux (something called linpus). Also one the cheaper version has wired keyboard. not too bothered about the price but want value for money. might also get a remote. I have read that the revo is no good for HD audio but i don't think this is a problem, i don't really know what it is. i will only listen in stereo via the TV for the foreseeable future. What version best suits my needs?
