I purchased an N810 instead of a smart phone because I the cellular carriers in the US continue to place restrictions on there operation and position things so that they are the recipients of all revenue from services of any kind. Even something simple like ring tones. Their solution is to have you pay more for 15 secs of sound than you pay for an entire song. They cripple the designed features of devices to eliminate or make difficult any DIY media. Apple won't permit iPhone applications that compete with those they've created. I'm through with closed devices. The N810 is totally open and remains that way because it isn't sold through carriers. The N810 even functions well as a VOIP phone. It even works with my Plantronics bluetooth head set. It's weak point as a phone is that it depends on WiFi. WiMax fixes that and for now voice messaging can fill those unconnected times for me. If I wanted to pay once again for Internet access with a cellular data plan I'd have full VOIP without any carrier imposed controls. The N810 overcomes the major problem with phones by eliminating the closed carrier. I see Nokia as a company with great vision verified by their success. The timing for an N900 is very good. The Android will pave they way for the open phone running Linux. The iPhone has already convinced the world that the best phone is a computer. Ubuntu is leading the charge to legitimize Linux for the average man. It's much to early to predict the death of the N series. With a SIM card an N900 is a ready made Android platform.
