Friend bought his first computer. What router does he need for AT&T DSL?

Apple Express. Done. Unless ATT has one for free.

I'll disagree. $100 router for a single $350 computer with a sub 6Mbps connection? Way overkill. If only requiring a single computer, simply use the provided modem. Unless it isn't a WiFi modem/router and such a connection is needed, then grab something sub $50.
To clarify my Airport Express stance. I own one, an older 802.11n model. Been a relatively pleasant experience for just over four years. While I don't discount the utility of such a device, without a clear need for any of the Express specific features, I would not go down that route.
