I have a 802.11b router at home (DLink DI-614+ (B rev)) and it is working perfectly well for me.
I want to replace it though, since it is out of updates, and now several years old and heck, I want a new toy to configure!
I was trying to decide what to get. I could care less about 802.11g or n support, since B is fast enough, but every device in my house is now B/G, so G would be fine for me. N buys me little to nothing. (Small enough house that range is a non-issue).
The features I realized I want are a USB port for sharing a USB hard drive. I would like to have a central device I could store files on. I do not want to waste the power of an always running PC to do this, so a router seems like the place to go.
I would love it, if it could support Vonage VOIP as well, then I could ditch a power brick from a second device (I have the small DLink Vonage VOIP box).
All the current examples of this router (with USB drive, yet to find one with VOIP too!) are in the $100+ range, and N and silly, when a B/G is in the $30 range around here.
