Okay. Total cost of ownership for 1 year on a Sidekick: $99 (after rebates) + ($40 x 12) = $579. That’s for one year, unlimited internet access. I have a feeling that T-Mobile would want to renegotiate a new 1-year agreement with you at the end of the year, or you would have to pay for your internet. That’s not as easy to justify, though I’m trying.
