I also use K9 on my Gemini. The scrolling is not so relevant for me since you can easily scroll through a mail using the touch screen. Another issue is that you cannot directly answer a mail in reading mode. The answer function is somehow hidden in landscape display. To answer a mail, you have to leave reading mode and go back to the message list. It somehow works but is a little bit less convenient. In general, I'm quite satisfied with my Gemini. However, I do not use it as my only mobile device to sompletely replace my smartphone. As a smartphone, I will keep using a Blackberry. The Gemini is rather for travelling to relieve me from the need to carry a laptop. You can indeed do a lot of things on the Gemini you cannot do this way on a smartphone. Most disappointing point for me is the poor support of external monitors and projectors. One intention to buy a Gemini was to use it as a presentation machine at meetings, conferences, etc. Unfortunately, this doesn't work.
