I think it's important to keep any eye on the Apple side, though I've always found Windows-based PCs to be more productive, given my work style (not to mention my job). But it's not really about work: I just prefer Windows, sorry. That said, Apple makes good stuff, and of course I'll be evaluating Leopard soon.
