I'm a Nokia fan. Have moved away in the past, but always seem to end up back with them.
When my contract was up last time, i had a look at available phones that would more enhance the Internet, E-Mail etc etc. I ended up at a Nokia E71. Yes, there were Blackberry's and the i Phone etc, but some were well out of what i would class a proper amount of money each month. Bear in mind though that i have to get 2, 1 for me, 1 for the wife.
It also meant i left O2, who i'd been with for years, to go to 3.
All in all i've had a good time and recommend the phone to people without hesitation.
When this contract is up, i may well move away from Nokia, to try something else again, but hey, by that time, they might have an i phone killer
