"Because the current USB 3.0 spec is currently not signed off, we're challenged and we won't have support for USB 3.0 in Windows 7 at RTM (release to manufacturing)," Lars Giusti of Microsoft said in a WinHEC session here titled "USB Technology Update and Windows Strategy."As far as booting goes, Windows or Linux, the best thing you can do to improve it is get an SSD. I've found it makes a world of difference.
Windows XP didn’t support Wifi until SP2 either, device manufacturers just provided their own drivers until then.
As far as SSD goes, I have a Dell Mini on an 8gig SSD, and I know it’s faster (though the small memory and limited processor limit it), but I don’t know if it’s worth the immense price differential from a regular drive yet.
