Portable Standing Laptop Desk?

[jaypreneur]

I'm not sure if anyone else hates sitting down all the time, but I really want to be able to stand while I'm working on my computer. However, is there anything that they sell to use on the go?

I would use something that could be put on top of a normal desk. But I can't seem to find anything that is really portable (fits in my bag)

Anyone know if something like this exists?

I use an ikea-esque wire rack. The small square one is very portable and is fully capable of supporting my netbook, but I got the larger rectangular one that has enough room for a lamp and a mouse too. It also has enough space to support my forearms.

Thanks for suggestion!
