Well, I have got some PCs (I couldn't count 'em on my hands). Most of them are oldies though (except my main notebook). Man, I couldn't live without having my own dedicated computer. Just the idea to share a device that I use day-by-day for long hours makes me sick.
To Redmage: Why don't you get a P3 or Athlon? It costs almost nothing (yes, if you're lucky, you can get it's parts for free), and it's fairly enough to do the most of your everyday computer activities (well if I don't count the resource hog games. Not very far ago, my main notebook gone bad, so I had to use a PII notebook with 192mb ram & 40gb hdd for 2 weeks, and I can tell you, it was fairly enough for browsing the web, downloading torrents, watching films, coding in C#, PHP, HTML, and even for doing basic Photoshop tasks.) If I were you, I'd consider this.
