The FitDesk company has sit-to-stand desks, under-the-desk ellipticals, and bike desks. Check out the video above for a FitDesk Product Review. I use my FitBike almost daily for reading, watching webinars, and processing emails. It folds up easily, so it doesn't take up much space. The rubberized desk keeps my laptop from sliding, and the additional side wings have a space for my notepad, pen, and drink. I've moved this around my house, putting it on my screened-in porch in nicer months and my office the rest of the year.
This bike isn't meant for a sweaty workout; it's meant for movement. I switched my seat to one that was more comfortable for me and highly recommend purchasing the seat adapter for people under 5'4.
