Can anyone recommend a wireless router for a new Macbook? I was looking at the Airport Express, but they don't seem to carry them at Best Buy anymore. They have the Airport Extreme, but it's $80 more and has many features that I don't think I'll need. Any suggestions? Is there any reason to stick to the Apple Airport series, or will any wireless router work just as well? Oh, and if it matters I've got cable internet service.
