Better define the target of IT Professional more closely then. I suspect you really mean full-on geek. It's certainly not intended for corporate IT use. The fact that Nokia deliberately do not support device locking, remote wipe or any other MS Exchange Security Policies means that connecting with a corporate mail server to synchronise mails, calendars and task lists is out of the question, and is a major factor why the N900 won't get a look in within the Enterprise space.
