Magnify text edit feature rocks
 

One thing I felt the D1 majorly lacked is the ability to scroll edit text entries. They clearly borrowed this feature from the iphone for the D2. I didn't even know that the feature was on the D2 until I found it accidentally. I had been wondering what the red bullseye in the text entry box was. It works great, almost just like the iphone. In case you all haven't tried it yet, just long press on the text in the text entry fields and it will magnify your text and allow you to scroll the cursor and place it anywhere in your text entry to edit. This os a HUGE plus for me.
In certain situations, the edit menu will pop up instead, but I think this is only on certain web text entries. Anytime you see the red bullseye, it will have the capability to scroll edit.
