To me it seems obvious that the next gen will include some kind of cell/long-range type communication, but I really wonder how useful (in the sales sense) it will be.

1. WI-Max? I live in New York and there is no rollout of this service.
2. At least in the US, cell type data service is still locked among the vendors, and either GSM or the other one (forgot). My point is that Nokia will have to sell multiple versions of the 900 depending upon carrier (and thus technology), and users will have to decide if they want to change cell phone plans to get the best rates.

Personally, I believe the 'tehered modem' is the short term way to go, hopefully with a new, faster version, of bluetooth. But ask me on another day, and I might have a different answer.
