After years of dealing with the limits of Blackberries, I finally broke down and bought a Droid X. At first, I thought it was great, but that only lasted until I actually started using it for work. I have to say that this is the worst smart phone I have ever had (I've had them for about 10 years). Most have been BB's, but I did own a Palm once.
The Droid is just not business friendly. First of all, you are forced to open a Gmail account in order to sync your calendar and contacts. I really loved having to do that. Half the time I can't get a data connection so I can't access the internet or send emails even though I have full bars. And, very often emails I am trying to send just get stuck in the outbox. Previously, I could reboot and then they would send. But, that doesn't even work now. Your ability to search emails is extremely limited. You can't sort emails (at least that I've been able to find).
For a $600 device, it is nothing more than a light-weight smart phone.
I was looking to roll out a standard smart phone and tablet to my entire sales team. Based on my experience with my Droid X, I am now probably going to go with iPhones and iPads.
