How about the bring back the unbloated OS? Notice how fast 95/98/XP are, and then you try out Vista or Win7, even on a multicore machine and it lags behind, not nearly as snappy.
Just spend time to give us a quick and unbloated operating system, with a classic interface. Even XP loaded with updates and patches is so much responsive than the newer versions of windoze.
Let have a smarter, quicker, classic OS, not a bloated, dumbed down, limited OS.
