I don't need and can't use a phone other than a company assigned one on a company wide network that is not supported by the N900.

I will be paying at least $700 for my next portable device so price isn't affecting my opinion... From what I have seen so far, traditional tablet usability may have been compromised in order to support costumer expectations of a cell phone. That certainly is the case with regard to visible things like screen size, d-pad, and function keys; I suspect it may also be the case with the firm/software its own dang self. I mean who wants a dialing pad for cell phone they can't use popping up because they moved the wrong way or an application developer is incorrectly calling an API?.

Other than a PIM, nothing seems revolutionary regarding application function over the existing N8** tablets. I also suspect that some versions of the new apps on the N900 will become available for N8** devices once developers familiar with both operating systems become more involved.

For a new internet tablet user, at almost $600 less, a used N8** is a bargain. For existing IT only users, as Sachin007 has posted earlier, an N900 really isn't a cost effective upgrade.

BTW, ^that is my opinion YMMV.
