I own both a Mac and a PC. I've used a PC for about 15 years and a Mac for about 3.
If I were to confess to how many machines I actually own, the number is probably in the low twenties, with multiple Win 2k, XP and even an old 98 box somewhere, several Linux servers, a Linux laptop, an HP-UX box and a Solaris 8 server that I've never bothered to update. Got geek?
But there are only two machines I use on a daily basis, and those are a Windows XP box and a PowerBook.
And I've got some complaints about both Microsoft and Apple. I'm going to warn you, this is a really geeky rant. And it's long.
