Take the concerns or misconceptions mentioned here and then amplify by a thousand. Nokia did underestimate the interest of the N900. Just imagine if Nokia had the foresight and actually marketed better and added the following phone features without removing any of the current good stuff:

1. Home call and end buttons (plenty of room on the front of device)
2. Phone centric profile option (key word is option)
3. MMS

The N900 would dominate, make geeks happy and smartphoners. Also reduce the concerns and complaint to a fraction of what they will probably be.

Whenever most of us get them of course.... whenever that is.
