Hi All,
I got my (unlocked, £500 worth) HD2 yesterday and it's going back.
I'm a long time HTC user (this was my 7th HTC device) and all I can say is (from my perspective) Windows Mobile/Phone and a capacitive screen do not mix. Tick boxes and drop down's are almost impossible to get (eg the arrow to get the keyboard options up).
HTC have really annoyed me by restricting my input options - admitedly, there are some that aren't so useable with this type of screen - but, annoyingly, not all keyboards are available in all applications anyway. And why oh why can't I use XT9 in (amongst other applications) opera????
Also, when selecting drop down menus (if successful) the keyboard pops up... EVERY TIME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The slide to unlock 'toggle' is at the top - not everyone has hands the size of Daron's!

so it's a real stretch to get it one handed, and if you connect to an exchange server that imposes security, you have to go through 2 security steps EVERY time you use the device - Slide to unlock & enter passcode...
Using Pocket Informant (by far the best PIM) is a nightmare on the HD2 as accurate selection is a elusive as an oily rat! - due to the capacitive screen and (possibly) the shape of my fingers. - it's just too easy to select the wrong apt/contact and delete them by mistake.
and to top it all off... Excel... don't even think about it! If you have locked headers and the zoom set to a level that you can actually read - the damn keyboard is so big, that you can only see & use maybe 3-4 rows.
TomTom navigator 7 not compatible (tomtom's fault)
ON THE UP SIDE!
FAST!!!! Lovely clear screen. BIG! (best used with 2 hands). Can be used as a WiFi Router (drool). Camera is good - bit of a blue tinge when using flash, but daylight pics are good - responsive too (unlike previous HTC cameras).
Conclusion:
For me, this would have been a fantastic device - with a resistive (or other stylus compatible) screen. If you can't realistically use this device for business and wanted it for multimedia - you may as well get an iPhone
So, I'm going back to my Touch HD with it's lovely integrated stylus....
