I'm looking for a small pc gamepad with dual psp style (actually something closer to the Caanoo would be preferable) control sticks. I'd like it to be as thin as possible (even if this hinders playability). The reason I'm looking for this is because I have a reasonably powerful laptop and when I fly or take a train I'm stuck using the lousy keyboard (unless i bring my xbox360 controller and dongle

).
Thanks
EDIT: forgot two key pieces of info. 1. I want it to be thin so I can carve a spot for it to be partially inserted into the laptop case. 2. preferably wireless using Bluetooth (dont want to have a dongle)
