some products I endorse:
GO 2.4 Optical Air Mouse and Compact Keyboard Suite The small keyboard is good for me because I was leaning to use the left side of the full keyboard AND it frees up the space where the number pad was so I can keep the mouse closer, making it more ergonomic. (UCLA has a great site devoted to ergonomics.) The mouse can be used on the table, in the air, or my favorite- on my leg. I haven't practiced enough with it in the air...
I also picked up some gloves at walgreen's post-halloween. They're painted to look like Mummy hands and have grip rubber on it so I'm wearing them backwards for better typing. They are working out great!! Warm hands that can still work thru gloves are A+ in my book.
here's what it all looks like:
