I've got 3 but 2 crapped out, so I guess that makes it 1 now.
Have a Powerbook 1400CS running painfully slow with bare essentials, a dead PowerMac 7500 (dead board) and a dead 400MHz iMac DV SE (dead board and fried monitor). I don't think I'll be getting another Mac for awhile but I enjoyed them when they worked. The 7500 was great for running Protools and Digi stuff. Oh yea, I've also got a dead Apple 1710AV monitor. That thing was a nightmare. It died on my 3 times within a year and had Apple replace the main deflector board or something several times. 3 years after I bought it, the extended warranty ran out. It was a very expensive 17" monitor. ($1000!!)
For now, I've got an Athlon setup now that I'm quite happy with running Sonar at the studio.
I'm open to checking them out again whenever I feel OSX feels snappier and more solidified with the apps I need.
