Why? Is it because it's very different to Windows? That would just be a case of finding your way around.
If it's something deeper, well, nothing wrong with that.
Personally I'm glad I can't afford one now. Means I have to save up and will (hopefully) have enough when the PowerBook G5 comes out. Way better than my current Toshiba Satellite A30 (which, trust me, is still pretty damn good).
As for style, the iBook will always look like a chopping board, and it's a pity the PowerBooks aren't Titanium any more...
Ah Mac...no viruses, no hardware compatibility issues, no Microsoft spyware campaigns, no bloatware... [dreams]
