for me, ive only ever seen the opposite of pretty much what everyone is saying here.
at work, we have 2 imac g5s, one powermac g5 adn my compac evo from like 2003 that i got for free out of the garbage, which was designed for windows NT (i put on XP)
the most stable computer at work is my laptop. the macs are grinding to a halt, slowing down, crashing quite often, and begining now to have severe hardware faults (all with the exception of one of the imacs which has sat unused in a closet since it was purchased in like 2004 then hooked up last month). my old and very abused compaq (i dropped it a few times so one of the rightclick buttens fell off, one of the HDD screws was loose so teh HDD fell out onto the floor once, i just slapped it back in and screwed it back on, the screen has burnmarks on it, im guessing from where an old tech put something with very heavy on it, and is covered with coffeestains, again im guessing from the old tech that it belonged to) is, however, chugging along fine with no issues whatsoever. runs smooth with XP, all apps open quickly, and im using the newest versions of all of them (much newer than the versions that are installed on the macs).
-i dont get the BSoD anymore, and i havent gotten one in YEARS, the only time i got one was when my video card fried, in the desktop PC i have at home, while i was playing a game, but i managed to slap a new one in and get it going again in less than 30 minutes
-all USB hardware works easily with my laptop
-a very non-invase, FREE, and good virus scanner keeps my systems protected (avast), but i usually never even run across a virus because i just know which sites are unreliable
-and swapping hardware is easier in my PC at home than it is at the imacs at work. i had to replace a broken imac HDD yesterday and it pretty much took all day to get it in, i am able to swap the primary drive on my PC at home, partition it, format it with my file system, install XP, and get it running with drivers, and browsers (not stuff like office, base running mode) in less than an afternoon.
also all of the computers in the room, mine, the imacs and the powermac are on an airport that connects to the buildings larger network. my laptop is the only computer connected to the airport that can see and connect to all of the computers on the larger network outside the airport. (and before you say that its because my laptop is authorized on the network, my laptop is the only computer there that HASNT been authorized to be on the larger network by the IT people in the building)

and for a computer that is stylish (aren't windows laptops atleast so bulky and horrible looking ?) they have a simple to use OS, and hardly ever crashes or catch virus' and because the majority of people use windows computers
