Matthew,

I've just got a Nokia 6610 (very similar to the 7210, but in more of a 'business'like package). Migrating from 2 previous Nokias, I find all the menus very intuitive, and love the predictive text. Battery life is excellent so far, tri-band works easily (auto-switches in Europe and US), and hands free is fine with the optional Nokia headset (the included earphones seem to be designed for the stereo radio, and are on an especially rubbery and tangle-prone lead )BUT I'm not sure it's very well built ... in fact, the 6610 seems to have now been withdrawn from sale in the UK

Colleague has a T68, which he thinks is great (but then he was coming from an old Motorola Timeport, so two tin cans and a piece of string would have represented an upgrade).

I don't think that you can really go wrong with either, but I would suggest that if you're used to (and happy with) the Ericcson interface, then stick with it.

Cheers
Stew
