Retired that P2 a couple years ago. BTW it still runs FINE being bought back in '97. This merely disproves the mis-dis-information/BS fanbois spread that only Macs last a long time, to justify paying double/triple or MORE for their Mac.....
I just replaced the beater box at my parents house with a 1.5 Ghz Celeron laptop with 1 GB of ram running a locked down Debian / KDE. It's drunken / moronic kinfolk and guest approved. I started leaving a beater box out at my parents place to keep people of their main system(s). It's worked great. That replaced a 700(?) Mhz 512 Mb (or 384 Mb) system of the same configuration. They both ran modern Debian OSes, and were good enough to surf the web, play music, use VLC, etc. They gimped out a bit with full screen streaming flash video, but oh well... No viruses, no drama, fully automated updates, and it's OK if they die...
The simple truth about Apple anything is this: Apple has a higher profit margins on hardware, and spends more per unit on advertising that anybody else. Every dollar spent there is a dollar not spent on the hardware. After that their money is spent on industrial design and component integration (of fairly standard components). At the end of the day, unless you really like their software / OSes, you're paying a big premium for modestly better industrial design and component selection (except for when it isn't). Anything else is just magical thinking / fanboyism.
Buying Apple anything to have to run Windows in an emulator (and spending most of your time in that), or buying Apple anything to install a Linux or BSD is just a waste of money. The question really boils down to how much of a premium are you willing to pay to run Apple OSes and software? In my case that number is less than zero. You'd have to pay me. For others the number can be different.
