I would have to say I am slow when it comes to being up with the times, at least with computers. Here are all the computers i have owned/used:
1. PowerMac 6100/66 [brothers first Mac]
2. PowerMac 6400/200 [bought new, for $2000, when i was 15 i think]
3. PowerMac G3 333 MT [was given to me, from my boss, in College]
4. PowerMac G3 350 B/W [bought on eBay, for $35, bought another from the MR market place for parts]
5. PowerMac G4 Dual 450 [i loved this machine, another buy form a College on eBay]
6. PowerBook G4 Titanium 450 [bought from a friend]
7. PowerBook G4 867 12" [eBay purchase]
8. PowerMac G4 Dual 1.42 [another great tower, hated it when i accidently fried it]
9. PowerMac G5 Dual 1.8 [my most recent computer, bought from another graphic designer]
I think i bought all these in a span of 6-8 years.
