I simply cannot say enough about what the Blackberry has done for both my business and my ability to parent/work more freely. Imagine that end of year school party--you really, really want to go, but you're waiting on an important offer via email. No longer will you feel chained to your desk, but with a more relaxed attitude can slip away, mid-work day, and be at the party. Or the school play or anything.Another scenario: it's a business travel day. You could be struggling with wireless at the airport, landing and feeling anxious about everything you're missing. Or...you can simply power up your blackberry and start answering emails while you're stuck on the runway waiting to pull into the gate.My sales have increased since I got the blackberry, but more than that, my mental health has improved. I utilize those "down moments" far more effectively thanks to the great rolodex feature (which syncs right up with Outlook!) That means time in the car or waiting around, you don't have to call the office to track down someone's number, you can simply hit the tracking wheel, decide if you want to email, phone--and if you want to phone, do you select mobile, office, or home.I have bought a blackberry for everyone on my staff, that's how much I believe in them! A MUST HAVE.If I could give six stars, I would!
