Outside Sales Rep. I spend about 150 days a year on the road. The more I can do on my phone, the less I need to do with my laptop. If I can get all of my work done before I get home, then I get more time to myself.
Our small rep agency uses Exchange through Office 365. My life is in mail, calendar, contacts, and excel. The 920 does a good job with all of these things, but it is far from perfect and still needs a lot of refinement.
