Input:
I bought mine at a local Micro Center.  I wish I'd looked here first.  The Linksys was easy to set up and would probably work fine for 99 percent of people.  I also like the fact that this is not an 802.11b base station.  I prefer to have the security option of unplugging the wireless base station and therefore it needs to be a separate physical box.
What about those 1 percent of users who won't like this product?  If you like to keep TCP connections open for a long time, e.g., if you're a developer using ssh or telnet, this Linksys is problematic.  My old SMC router, after upgrading the firmware, was rock solid and I could keep an Emacs up and running on a remote server for days or weeks.  With the Linksys connections will mysteriously die.  I haven't changed my cable modem or my cable service.
