Now while there were things about the BB that I didn't like, there are some things that the Blackberry does very well though.
a) Its a fantastic phone. Great RF, clear calls, no drops, and real keys so dial without looking (like when you're driving - not that I condone driving and talking on the phone)
b) speaking of driving, you can also program the shortcut key to launch voice dial so if you're in the car a lot you just hit the voice dial key, say the name and it dials for you. No need to take your eyes off the road
c) of course while driving you should always use a bluetooth headset and the BB's have a rock solid bluetooth stack. The headset & phone have never lost their pairing. The iPhone is ok, but its lost the pairing once or twice
d) With real keys you can answer the phone or dial with gloved hands in winter (not possible with the iPhone though if you have a sharp enough chin it works to hit the answer button)
e) Many BBs have a rubberized casing on the back/sides so its not as slippery to hold when you fish it out of your pocket
f) When you're on the road and run out of battery you can easily pop in a replacement. If you don't have a replacement, it charges via a standard mini USB which is available almost everywhere. I use my RAZR charger or the miniUSB cord for my digicam to charge from the PC
g) The BB is designed as a one-handed device. Other than typing (which you can do slowly with one hand) you never have to use 2 hands.
h) If you are an IM (instant messaging) addict the BB is fantastic. Using either the free IM clients from RIM or BeeJive you can be connected 24x7. It runs in the background too.
