That "peddling add-ons" thing may work for most of your stuff, Microsoft, but when it comes to paying $90 for a wi-fi adapter, the argument gets a little shaky.

The PS3 has built-in wi-fi. The Wii has it. The PSP has it. Heck, even the DS has it, making the prospect of spending $90 on Microsoft's "add-on" as surprising as it is ridiculous.

But there's a way around it. A few ways, in fact. All of them involve buying routers or third-party adapters, and all involve more fiddling around than the official solution's plug-n-play, but does that matter? Every time you look at the setup hassles and baulk at the process, try and remember you'll baulk more at paying $90 for a wi-fi adapter.
