I was, of course, tempted by the T-Mobile Sidekick, which is currently free at Amazon after rebates, and spent quite a while this afternoon reading all the customer reviews. They seemed to be about half positive and half negative, with not too many in between.

I wasn't going to get one, because although it looks like a cool gadget, it looks WAY too clunky to use for a phone, and the monthly service charge is a fairly significant committment, but then I noticed that I can't have one, even if I DID want it ("Sorry! This product is not available for Shawnee Mission, KS").

At least now I can quite worrying about passing up such a great deal.
