Here is a cool Outlook tip when using you M200 in tablet mode.
By default the button above the joystick is configured to type the escape key. If you go to the Tablet and Pen Settings Control Panel, you can change this to type delete. This basically allows you to rapidly read and delete items in Outlook w/o using the pen. Instead you use the joystick to move around outlook, and then the button above it to delete mail.
I scan and delete a lot of mail in Outlook and find doing it in Tablet mode very comfortable. I did this for about 2 hours on a recent flight. It was really a nice setup since I was on an American Airlines flight with Less Room Throughout Coach (don’t ask, it was a ghetto 757).
