I recently upgraded from Windows to a Mac, and now I have two Macbooks. Would they work better with my wireless if I got an Apple Airport a/b/n router? (I couldn't find anything about this on Google or anywhere else.)
It's not so much that AirPort routers will work "better", but I can guarantee that setup of AirPort routers when using Mac computers is much easier than other routers. The AirPort Utility really makes setup a breeze!
This comes from years of experience as a network admin and having personally owned/used at least one of just about every major brand of home router. If you can afford an AirPort router, you won't regret the purchase.
The Apple Airport router will work better in the sense that it allows you to use some additional features, including "Wake on Demand" (included with Snow Leopard):
The Wake on Demand feature of Mac OS X v10.6 Snow Leopard lets your Mac continue to share items (such as music, printers, files, or your screen) when it is asleep.
