Blackberries are very good for those who travel, you can get packages like blackberry world service which give you unlimited email and BBM and a limited amount of 3G web browsing even in countries where it's usually expensive to roam.

That can be worth it for a number of people. Plenty of people need access to email even whilst on holiday, and BBM can be a simple way to keep in touch.

I got rid of my Blackberry Bold 9700 a few weeks ago and replaced it with an iPhone 4.

The main reason for moving away from BB was the shockingly poor internet - I used to pay for the internet service and could only use it about 10% of the time as it was dire (slow and buggy).

iPhone internet on the other hand is fab - even works very well on my train in to work in the mornings.

Also, enjoy iPhone's larger screen and true Push email/contacts/etc for my Hotmail rather than BIS.

Apps are a lot better on iPhone.

BBM on Blackberry was good and I still use it on my work BB, and WhatsApp on iPhone.
