Hmm, they deleted my post for some reason.
I can relate to that, My grandmother's late 2006 iMac (the one I have right now) started having the lines problem and Apple said that they wouldn't fix it for free. So this past Christmas, I gave her my new Mac Mini and she gave me her old iMac. The day I got her old iMac, I call up Apple support and they then said that they would fix it for free.
Still, I love the pre-unibody designs of PowerBooks and MacBook Pros. To be honest, I'd chose a 17" PowerBook G4 over a new 21" iMac anyday. They still have a lot of potential if you upgrade them.
My 12" still works fine, though it's off a lot since I haven't used my computers a lot lately, I have an iMac G3 running Tiger set up beside my bed for email and web browsing when I wake up in the morning and since the bed is so comfy, I rarely use my desk setup lately as I have been distracted by other things.
Anyways the macs I still need to collect are:
17" PowerBook G4
PowerBook G3
PowerMac G4 Cube
PowerMac G4 MDD
and you can add to the list a 8-Core Mac Pro w/ 3x30" Apple Cinema Displays. I hate the new 24" LED design, the metal design is so much better IMO.
