WinXP is obsolete... its over 5 years old... Why didn't he review Vista?
It doesn't ship with any notebooks yet. IOW, he's trying to tell people about what's best now.
It sounds as if Vista is going to be a nightmare -- requires twice as much or more RAM than current XP machines and there will be seven (7) versions (IIRC) for just about every type of user instead of the two for XP. I read an article on here that chronicles how long it took to decide how many "off" buttons are shown after a user hits "start" to beginning shutting down the machine.
Someone pointed out that having too many versions, as Vista will have, complicates a buyers decision making to the point that he/she will either go somewhere else (a MAC??) or put off the purchase completely. XP will be around for several years yet. Just as MS stopped supporting Win98, XP will one day not be supported. If Mac can get a replacement computer out that will compete with the complex Vista operating system and runs Windows programs easily, maybe they will once again become a real competitor to the Microsoft giant.
Because, unless you are either in the Vista beta program or have a volume license, it is not available yet.
Vista is obsolete too.
