Well, kudos to the MorphOS team for this. Unlike Hyperion, they at least get part of the equation: inexpensive hardware, as opposed to modern inexpensive hardware. Unfortunately for me, I hate all of the uni-body Macs, so I doubt I'd get one even if I had room on my desk for it. (I'm more likely to get a Power G4 since it can hide under my desk).
Good luck guys. Might wanna publish your sales figures just to let everyone know, especially if they go up as a result.
