Contemplating Apple

I realized this weekend, after spending countless hours waiting for my home PC to slice and dice images for a project I’m working on, maybe it’s time to think about a new computer?

Once I tallied up the total time spent on the project (and I’m still only 1/2 done), I realized I could have been complete in a weekend if I had an Apple.

Gulp.
Dare I consider the possibiities?
I’m looking for an iMac G5 - it can be used, of course, I don’t need to drink from the Chalice of Macintosh just yet…. i’d like to dip my toes in though.
