Here are all the Macs that I have gotten since I switched to Apple in 2004.
Power My G4 Cube (Fall 2004/ 4 years running)

- My first Macintosh ever and probably my favorite Mac to this day! At the time I was sick of Windows and Linux just wasn't appealing. This computer was giving to me as gift from my family and it was bought on eBay for 150 bucks. I switched to the Mac OS X and I never looked back

!!! I still have that computer today, its running 10.5.2 with the original 450Mhz CPU, 512mb ram, and I upgraded the 10gb hard drive to a Seagate Barracuda 120gb hard drive. Currently that is my music server. I have left this computer running since 10.4 came out so just over 4 months, it never breaks! I did add a fan in the bottom which drastically cooled the entire unit down!
iBook G3 500Mhz (Spring 2005/ 3 years running) - I bought this off of eBay shortly after getting my Power Mac G4 cube. This computer was so I could got to class and take notes. Had a 40gb hard drive and I installed 512mb ram. Battery worked pretty well, but I love this laptop. Ended up selling to my Dad, told him if he ever gets another laptop I want that one back. I miss that iBook.
iBook G4 1.25Ghz (Fall 2005/ 1 year till sold) - I got this after I sold my Dad my G3 iBook. I used this laptop for over a year, and I still regret selling that computer, really wished I kept it, it worked like a dream and the only problem I had was the hard drive failed when a class mate accidentally knocked it off the my desk onto the floor. Upgraded that computer to 1gb of ram, and that computer FLEW.
Macbook CD 2.0Ghz (Fall 2006/ 2 years running) - Still have this laptop, I have dropped this computer more than I can remember or count and yet it has never had a problem. I have scratched the screen pretty bad and cracked alot of the plastic (due to travels alot for my job). I bought this Senior year of college and I still have this computer, going on 2 years and it still works great. Don't really know what to with this machine, thinking about just fixing it up because its a really great laptop. I love this laptop, only second to my G4 iBook. Not sure which I like more . . .
2x iMac G3 333Mhz (Spring 2007/ 1 year till given away) - Got these two iMacs (Blue) from a friend, used them for a while, didn't really need them, upgrade the hard drives to 40gbs(had them laying around) ended up giving them away, just because I did not have room for them, they worked great, only had a little screen burn image.
Power Mac G4 733Mhz Digital Audio (Spring 2007/ 1 year running) - Picked this one up from eBay this summer for 50 bucks. It had a bad hard drive, so I replaced the hard drive, installed OS X 10.4 and later 10.5.2, it was my DVR for EyeTV unit until 3 weeks ago. Don't know what to this computer, it was a tank, never once gave me a problem, great computer.
Power Mac Dual G5 1.8Ghz (Spring 2008/ 3 weeks running) - Got this 3 weeks ago this in now my main DVR unit for EyeTV. Got it so I could decrease editing time for editing tv shows and then last week I found a program that can automatically edit commercials

. . . however it is nice to be able to recording a tv show, automatically editing the commercials, encoding other shows already edited and watch a recording in iTunes at the same time without skipping a beat. This Power Mac Dual G5 is a Tank. OH also is the 8 dimm ram slot model, not the 4!!! So far only had one problem with the computer turning into a freaking 747, however I changed some power settings and it seems to have solved that issue perfectly!
Considering I started using Macs in 2004, I have owned a ton of them, I have never once thought about going back to Windows. I use Windows at work and I am so happy when I come home to use my Macs, they just work . . . period, yeah you might have to tweak a setting here or there but they work great. Overall in reliability I think I have just been insanely lucky, especially with some of the nightmare issues I heard about the MacBook.
Thanks
