I have an eeepc which runs ubunto and xandros (dual boot) i installed compiz which gives the same abilities as described. it looks neat and certainly has no real processor over heads in the linux world but i have no idea what this would do to windows.
the thing i cant understand is if linux can do all these effects on an ancient intel graphics card with no real power why does vista require a 75 quid gfx card to run its second rate effects?
but at the end of the day apart from showing off the effects at conferences i cant see what use it is…
