There are lots of WiFi devices that don't do N. (XBox360 WII older PCs)

If you wire your G base station to your time capsule, you can make a dual-band network and get the best of both worlds.

Both are wired to my flats internal gigabit network. I don't need the G network for much: my iPhone is one of the last devices. My XBox 360, printer, Mac Mini and old MBP (running TVs/media playback), PowerBook G4 (internet proxy/cache) and Broadband modem are all on the wired network. Wifi is only for mobile devices for me...
 
I planned on doing the same thing, running a strictly 802.11n network, until now. Running only would help my signal strength as well as just keep random people from jumping on my network since no one I know has any n hardware.

Making it an option would be nice, "g" or "n" depending how much power you wanted to consume.

Plus, moving files to and from the phone via wifi would actually be fast.
 
I had my Linksys WRT160n wireless router set to mixed b/g/n and my iPhone wouldn't stay connected to my network after a few weeks of working, even at times asking for the password and not excepting it. Changing the router to mixed b/g, my iPhone is now working great with my network again. Seems like mixed b/g/n would work like mixed b/g with the iPhone, so I am not sure what the issue is.
