Hi, my Orange contract has now come to an end and I am therefore eligible to upgrade my phone. Available to me and I believe meeting my requirements are the HTC Touch Diamond, Samsung Omnia, Samsung Tocco F480.
The phone is mainly for business usage, and I therefore need it to be reasonably easy to operate, email access via 3G & WiFi, touch screen, on-screen qwerty keyboard, easy to write emails and texting.
Decent camera and video capability would be great but not essential. Won't be used for music at all. Currently I just use my phone for calls and texts, and my main reason for change is having to cart a laptop everywhere with me and trying to hunt down Macdonalds for free wifi!

I've read a few reviews of all the phones now and there seem to be a number of pros and cons for all. One of the biggest cons for me (and users may tell me different

) is the external stylus on the Omnia, as surely it's difficult to write emails without it? However that is the phone that seems to be the better of the 3 from the reviews I've seen.
My main concerns are regarding usability and reliability, so any advice or opinions would be gratefully received.
Also are there any phones on the horizon that I should perhaps hang on for?
Thanks.
