Thanks for all the suggetions and recomendations.
I took a wander down to my o2 store in Swansea and had a good play with the phones in the shop (yes the real ones not the display models
)
I made some enquiries about the Dell - but that apparently has some firmware options so I was told to ignore that one.
Had a brief play with a blackberry touchscreen - not bad.
iPhone 4 - already had seen a few mates.
Now the surprising one was the HTC HD7. I'd always been sceptical as I had an HTC about 4 years ago and didn't really like it at all. However this thing was something else. Got to say I was very impressed.
