Of course Windows has problems, but you people seem to be forgetting one important issue... Windows is A LOT BETTER than it used to be! Of course I don't know, but I suspect that a lot of you people in this forum do not use PCs regularly. Perhaps you made the switch to Apple when Windows ME or 98 were out, and decided not to put up with a faulty OS anymore. That's fair enough, because those OSs did really suck. But XP is very secure, in fact, it's the most secure OS Windows has so far built, with very few faults in it.
Secondly, the reason Apple computers have so little problems with crashing compared to Windows computers is that with a Mac practically every software product you need comes standard. Windows cannot do that because it wouldn't be fair competition. If Windows decided to build their own antivirus program they would have Norton and all the other antivirus companies on their tails for creating a monopoly. The same goes with practically any piece of software they can add. In Europe they're not even allowed to include Media Player. This means that when people buy a PC and expect it to be ready to go right away, they're gonna get dissapointed, big time. They think that the antivirus software included is enough, not knowing that Windows, by law, are not allowed to make an antivirus system that actually works. Then they curse their new computer to hell when it crashes four minutes after being connected to the Internet. (Seriously, four minutes is the average time a computer lasts online without protection.)
If you buy the necessary antivrus software when buying a PC, and buy proper third party software from known and trusted developers rather than download random stuff on the internet, Windows XP is gonna work fine for you.
