Hi, I've been reading MacRumors forums for about 6 months now and decided I'd post something. I'm planning on buying a Powerbook soon, but friends of mine that have them have trouble getting good airport reception in coffeeshops and such while people with other laptops get way more in the same place. The dorm I'm staying in at college next year has wireless instead of ethernet, so I'm worried about signal strength. Has anyone heard of anything you can buy to enhance the reception of your airport card, like an antenna or something? I looked on the applestore but couldn't really find anything. Thanks.
