Oh yeah, our current specs should support X64 or Longhorn. I'm sure they will also include basic drivers for CD ROMS, mouse, display adapters, etc. Yeah, we should wait for Longhorn to come out. That will be a significant upgrade as far as OS goes. I just hope I can afford to buy one.
From looking at your specs, you have a much better setup in every category except for RAM and DVD burner. We have the same in that department. Those Raptor drives probably kick ass but so expensive. I know that hard drive technology will start changing next year so be on the lookout for that.
