I'm planning to get a Acer A150 120GB model. I'm hoping to upgrade OS from Linpus lite to something a bit better. Been reading a few threads and some people seem to have slow machines running a slim down, graphically simple Windows XP installation while other are running Vista with full aero. Is this due to the difference between the ssd and hdd version? What OS would you recommend for the 120GB model? Can Vista be run at a decent speed? Windows XP (nlited?) TinyXP Vista - w/wo aero Windows 7 Thanks
