Why don’t people just buy a new computer — all new hardware — with the new system installed, and just copy their old files to the new computer? I’ve seen people fuss over compatibility and don’t understand them at all.
When I get a notion to try Windows 7 I’ll just buy a notebook.
On second thought, I’m not toting a notebook around with me...until it’s small enough to fit in a gun! :)
One, most OEMs ship computers with a bunch of crapware trial versions, etc., installed. Two, for many people, their current hardware is enough.
