This should be well received by consumers, in particular tech enthusiasts. I dont know what worldwide cell carriers will think, but I can tell you right now that the providers in Canada will resist this thing like its H1N1!
The tradeoff for my grandfathered, blink-and-theyll-take-it-away, $15 unlimited 'on-device' data plan is 8$/MB tethering (there are ways around that in windows mobile, but dont tell telus).
Id bet good $$ that if I were to get this phone on my plan, and if telus found out its a phone with true desktop functionality, they would try2 call it tethering (or using my smartphone plan on a PC), and deliver me a 5 digit bill. Really theres no way they would allow it on a voice/smartphone plan.
OTOH, without the voice plan they charge $30/month for 500MB(!) for a 3g data stick. Going that route I think I would prefer data only on a net/notebook then on this.
