Lapdesk for a notebook?

My old lapdesk that I use for my notebook is pretty worn out. I’m looking for a new one - something large enough to be able to use a mouse, preferably that opens up so that I can store stuff in it rather than on the floor next to my chair.

Anybody have a good one that they purchased either online or in some chain store?

W-w-w-w-walmart!

I’ve got one that is a lapdesk top, with a beanbag cushion underneath that attaches with velcro. Big enough for my macbook and mouse. Nice because you can smush it around and make it fit the angle you want it and however you’re sitting.
