I've newer seen a tablet or non-specialist laptop PC with a video in.

I have used my netbook to show the video from my PSR3000 using a cheap USB video capture device (UK £25) and the free VirtualDub software to show a video preview. Works Ok but there's a lot of bits to cart around and connect up.

The "EasyCAP" brand appears quite often at the budget end http://linuxtv.org/wiki/index.php/Easycap, and my thing uses the "empia" chipset mentioned as one of the versions of the easycap device.

I have no idea whether such a device would work with an iPad or android tablet. The page I've linked to discusses use with Linux so there might be some Android support out there although android support for anything other than storage devices is pretty terrible so I souldn't be optimistic. I did a quick google for "easycap ipad" with no obvious success either.

I now use a cheap 10" digital TV with AV input. UK £90. I'd recommend this approach as the simplest answer although as mentioned above posrtable DVD players usually have AV in and so would also work fine.
