I do own one but i bought mine around the middle of this year so i haven't had it for that long. I have done quite a few things to it since i bought it.
I originally paid $369/£190 for a 466 Key lime Clamshell that came with 64MB of ram, 10GB hard drive and no disks. I also had to pay £100 shipping and duty tax to get the clamshell to the UK so i really paid £290 including the shipping and tax. I also had to buy an Airport card for it (i bought a Buffalo Airport card for it at first but then i managed to snag an Apple Airport card for a fair price so i sold the Buffalo card in the end), new 60GB 5,400rpm hard drive, 512ram upgrade, OSX and OS9 disks, new YoYo and a change of covers as the one it came with had ink on it that could not be removed. I also bought an external CD-RW for it as well.
I am not sure how long i am going to keep it though. It performs well for most tasks is fine for iTunes and it can even handle Photoshop. I had to use it for two weeks when my CD MBP that i owned was in service once and it performed very well.
I don't use it hardly at all these days though just to discharge the battery etc or when i have visitors round who require the use of another laptop then it will come out.
It is a lovely little thing though and i really love the design. I have had offers from my family members to buy it as they all love it as it is original and unusual.
