VirtualPC Could be a solution for some, but I'm putting together a mobile engineering workstation for use re. my day job, and I don't think emulation on an iBook would offer the performance to make that bearable. There's a couple other reasons I chose this particular laptop that the iBook wouldn't have matched either, but the big deciding factor was engineering software and performance. Perhaps after Apple's laptops go x86 and Windows can run directly or VirtualPC won't suffer CPU emulation performance hit, then I can reconsider.
