It shouldn't be THAT difficult for Nokia to do, they've had TV Out on their high end phones since 2006, and they're now including TV Out on their mid-range phones too like the 6220 and 6500 Slide. Both of those phones cost less than the N810.

I think someone said that there's a chip in the N800 and N810 which is the same chip used to provide TV Out on the N95 smartphone, so in theory the tablets already have TV Out hardware, but it's not connected to anything.

I'd prefer actual TV output instead of VGA because it's quite tricky to find computer monitors when you're out and about. Practically all TV sets (even older models) are compatible with composite or SCART, so they'd all work with TV Out that used composite.

If you're stuck in a hotel, they're unlikely to have a VGA monitor or TV with monitor input.
