The N900 is not a Phone. Well that's not quite correct. It's more than a phone. The N900 is the first true communucations device for the Internet/Cell phone era. It's all due to RTCOMM which built on top of Telepathy. A communcation's framework. To which Nokia has added the Cellular protocol.

When I want to communicate with one of my contacts, I don't have to think about it. I don't have to worry about how I'm going to communucate with him. IM? Need to fire my IM applications. SMS? Well go into the messaging application. Voice? Bring up the phone app and place the call. The N900 elimiates all of that because everything is integrated together. I goto my contact and choose how I can to communicate and the RTCOMM does the rest.

When I finally got my N900, added some of my IM and VoIP accounts, I say the Call Type bar on the Phone App's Dial Pad. I was able to choose how a voice call could be made. That's when it the full ramifications of RTCOMM and the N900 hit me. It's a communication device. We can easily add new protocols by just adding a plugin into Telepathy. Then all of the N900 apps know of it and can use it.

AIM, MSN, ICQ, IRC, Google Talk, Cellular, SMS, etc. All at the touch of your finger on one device, and single applications (i.e. Voice, Messaging, etc). The application integration potential is mind boggling.

I'm very willing to bet I'll see 'telepathy-plugin-google-voice' in the very near future. I wonder who will be the first. One of our own at Maemo or Google itself.
