Both of you should check this out: http://www.amazon.com/Logitech-939-000181-Portable-Lapdesk-N315/dp/B002NTADVW/ref=sr_1_2?ie=UTF8&qid=1359395384&sr=8-2&keywords=logitech+desk.
I tested with a Surface RT, and this works pretty good. Makes it possible to use the tablet like a laptop, IMHO. The pull out mouse tray also means I can use a mouse with my laptop or maybe eventually with a Surface.
If I get a Surface, it will be a development device. I don't really care to develop for more than an hour or so with a laptop, so it will be used most of "docked" on my desktop, but with that tray, I can do the odd bit of development with the Surface in my lap.
I'm still not sold that the Surface is the Win8 device I'll get, though.
