Got the BB Bold 2 days ago. Pretty impressed. Other than the form factor (very wide and big), this is an amazing device. Messaging is first-rate, WiFi, 3G and an absolutely delightful screen. Keys and keyboard are nice, though since I am transitioning from BB Pearl, so it will take a little getting used to.
I got this device up on my enterprise server, and literally in 2 mins flat, after activating my enterprise connection, all my contacts, calendars, messages etc were in it. Very seamless.
Still haven't sync'd with a desktop for music or other data trasnfer, but can already use it as a media storage, just by connecting through USB for recharge. Very neat.
Can't say. I have been on Blackberry for many years now, primarily because my company has BlackBerry email server which pushes all corporate email instantaneously to my phone. So in a way, BlackBerry devices are pretty much the only smartphones that make sense for me.
I haven't used Nokia in a while. They are good phones. Their smartphones are really neat. They are just not for me (reason above), but for you they may be perfect.
