Maybe so they won't cover up the WiFi-antenna?

Same here, the Touch Diamond with Duttys Diamond ROM V1.6 and some registry tweaks (using TF3D Config) make it so much more responsive then you see on about every video review, Although for some people it might be a PITA to flash their rom it really is amazing having TouchFlo 3D as it was supposed to be.

Oh and in the 1.5 years I've been using WinMo devices I've honestly never had a crash during a call, so I don't know what that's all about.

I really can't say much about the Touch because I've never used one but the Diamond's text input works relatively fast. As long as you don't use the full qwerty keyboard, which is just too small for a 2.8'' screen, but the 'Compact QWERTY' and the 'Phone Keypad' (using T9), you're good.

But then of course, the Touch Diamond isn't really aimed at busy businessmen who need to type things fast/are looking for a blackberry replacement, that's where the Touch Pro comes in.

Exactly, and that is the case with every swipe-able app on the Touch Diamond. Of course there is a small lag but what most people regard as 'the' lag is that it the menu/photo/whatever doesn't move unless you make the full swipe first.

Also I must say that with a custom rom and some tweaks my Touch Diamond is pretty snappy.
