OK, I have a 17" Powerbook, and for the most part I still love it. I bought Applecare for it, and I still have about 4 months left on it. The machine has been so stable and trouble-free, I feel like I wasted my money on Applecare. But, somehow, I know if I hadn't bought it, the thing would have blown the logic board about 3 days after the warranty ran out. Anyway, the only nitpick I have about the Powerbook is that one or two keys on the keyboard are a bit difficult to push at times. This, of course, tends to make my typing look even worse than it really is. This isn't really that big a deal, since I can usually just press a bit harder on the keys to make them work. My question is: Should I take it in and have the fine folks in the Apple Store check it out while I still have AppleCare on it? It seems a bit trivial to me, but I'm afraid the keyboard will get worse after AppleCare runs out, and I'll be stuck with a busted keyboard. Any suggestions?
