I use this more for staying up to date with enterprise/personal email and on that measure it's an enthusiastic 5! When I have the Q with me at work, the emails show up on my Q before they show up in my Outlook in box. It's a great tool to have with you when traveling. It certainly beats lugging the notebook around (who would have ever thought we'd say that?). I can't be more happy with my Q and (so far) with the performance of it on the Sprint network.
