Well, since I was upgrade eligible, I picked up one of these for $0, no sales tax, said "no thank you" to the accessories & protection plan (at $9.99 a month!!!), kept my $15/mo data plan, and left for a grand total of $0. Yes, I may have an extra $18 on my carrier bill... seems worth it compared to the $100-$200 cost of anything competitive like an Atrix or Infuse.
Working out nice for me so far, and I can give my old HTC Aria to the kids as a MP3/game device. Trolls, you can go back to your cave now.
