I am thinking of getting a 7100i, does the datebook sync with outlook. I currently use outlook as my calendar and for tasks, and am wondering if those items will sync together. When I was looking at the Nextel web site, it looked like it did not sync together.

Yes, all BlackBerrys sync with Outlook. The Intellisync program is built into the included Desktop Manager and can sync calendar, contacts, notes and tasks via the USB connection.
