I'm about to pull the trigger on a MacBook. I know they may have a new model coming out next month, but I really can't wait as I need it for work. 3 questions: 1. On Apple Store, the reviews for the AC Adapters say that they're unreliable, melt down, catch fire, etc. Is this still a concern, or has Apple fixed it? 2. If I get Apple Care, but then throw in a 320GB 7.2k Seagate down the road, is that going to void the Apple Care? 3. How good are the Bookendz docking stations for the MacBook? At $150, it's a little pricey considering I still have to buy the spare AC Adapter, but if it works well, it would simplify things. Thanks in advance!
