R> New phone advice por favor.

See, I'm tired of my current phone. Earlier today I walked into a nearby T-Mobile store and asked about an upgrade.

After talking with her I came to three phones I liked at first glance, and I'd like SP's input.

 This is my current phone

The three phones I saw that I liked are:

 Nokia E73 Mode

Which would be "Free" pending a 50.00 mail-in rebate, and a data plan would be required.

 T-Mobile Comet

There is no mail-in rebate, but it'd cost 19.99 for it. once again, data plan is required.

and

 The Garminfone

I already have a GPS, so this phone really served no purpose for me, but I mention it as I always forget my GPS when I need it.

I've read reviews for the first two phones on engadget's website (or blog? iuno. I googled for reviews and that was the first result for both), and so far the E73 Mode seems the better phone and the one I like the most. I know that it'd cost more than ~$50 when I choose to get it, and that the rebate for the phone is only the 50 for the phone itself, but I'd like to know if anyone has any experience themselves, or knows anyone who has any experience with this phone.
