Need to upgrade from a 'standard' mobile to a phone of this type. I'll be using it for,
Calls and text
link up with work from site.
Emails
Camera
Any opinions?

a guy I work with has got one, I used to have an HD

it Looks! Mahooosive! not much bigger in reality than an iPhone but it does look it.
he's happy with it
can't say much more than that tbh

I've gone Android personally, Hero at the mo waiting for Nexus/Desire to be in the wild for a bit then I may upgrade to one of those

got one – love it.

Good camera, seamless email, good browsing.

It's awesome. I use Swype to type with, everything else I find a little fiddly. If you want something for lots of typing with, there may be better options. I had a Touch Pro 2 before the HD2 and that was very good for typing with the slidey keyboard, but doesn't compare tot he HD2 in other areas, such as performance, ease of sue and that huge screen of joy!

Got one too, Love it…

Just add i got fat fingers and have no issue typing with it…

You should try Swype, it's free (www.xda-developers.com) and you might find it works even better. Instead of tapping away you slide from one letter to the next keeping your finger on the screen, it gets the word right a lot more often than the standard guessamatic keyboard.

got one too, love it.

excellent camera, quick for picking up GPS signals, push email for exchange servers (and can be set for pop email too)

big battery option available if you find you chew through it too quick.
it is big, but i got used to it quickly (had a Touch Diamond before which is tiny)
