We currently have quite a few 7290's deployed in the company I work for.
The users tend to also get a Nokia 62xx for voice calls also as they tend to not like using the blackberry as a phone.
We have been evaluating the 8707v with the aim of replacing both devices with one device.
The device itself seems good but I've been disapointed with the battery life so far.
I also feel that the users "prefer" the nokia user interface for making/receiving calls and thus I'm interestd in the Nokia E61 and so I have a few questions:

1) Does the device sync all bes items (email/Cal/Contacts/tasks/notes etc)
2) Does the sync work both ways? eg if i edit a contact does it go back up to the bes and then into my exchange box?
3) How long does the battery last when using it for email for two hours a day?
4) how reliable is the 2G > 3G network switching?


Thanks in advance.
