This could be an interesting thread. Question: What infuriates you about your Mac? (Because we have too many "Avaunt, evil Windows user! Nothing goes wrong with a Mac. Ever. Really." situations.) However, it doesn't just have to be "X OS does this more easily than OS X (or 9 )" - you are entitled to think of your own most-wanted features . You can complain about things common to all computers, too. For me? It's the indicator lights, which shine all night (sleep & power charger on iBook, not to mention peripherals), without any option anywhere to turn them off. Apple needs to include a v. detailed 'how to carefully arrange blankets over screen' guide with each new computer purchase.
