Just got an 8110 on upgrade through Vodafone, and I manage about 400 BlackBerrys of various types for my company.
Excellent handsets, the typing on the 81xx takes a little getting used to but it does everything you could need very well, just doesn't have the 'wow' factor for some people and the camera is a 2mp job - but does take a lot better pics than a Nokia 2mp. Lots of scope to change it all around to your liking, plus loads of software available online too. It's also surprisingly light and the battery is 3-4 days of average use including spending 2 hours a day on the train.
You can tell that it's a business or 'prosumer' phone and not a fashion accessory but these days most phones seem to be either huge, complex and slow or pretty but vacant but this one does everything with no significant compromises IMO
This is my final choice of upgrade, in a month I went from a K800i to W960i to Nokia 6500 and then the 8110 and that's where I'm staying now!
