I made the switch to Iphone after many years of loyal BB usage. I have not been wowed, and the switch has been a lot more trouble than I expected. Aside from the service outages caused by everyone trying to switch on Friday, I've had a lot of glitches syncing email, etc.
One of the glitches caused a battery drainage problem. I went golfing on Saturday morning (so no phone usage), but my phone ran from 100% to 20% in six hours.
Another glitch was that the iphone was not compatible with my office email server settings so I had to reconfigure.
I'm also not sold on the form factor. The iphone looks "gay" (as one friend called it) in white. The elongated screen makes it look more delicate.
I got my balls busted by a few peeps prefer to correspond with me by BBM. Whatsapp is NOT BBM. Worse yet, Whatsapp on Iphone is not as good as it is on BB! (navigating, status profiles, etc).
So, long story short is...I'll be keeping my BB at least for a while and running both phones.....
@ Madman - Good question! I've wondered that myself. From what I've been told, customization is frequently mentioned. But, what and how often would I customize? I want things to work right out of the box. I don't have time and I'm not inclined to screw around.
