On that note (touchscreen computing), I'm looking to build a
touchscreen-driven, freestanding jukebox appliance, and the major
stumbling-block appears to be figuring out what touchscreen device
I should use: there are plenty of touchscreen LCD monitors available
on the market, today, and it looks like the `touch' part is basically
always (some sort of) a USB device..., but it's never quite clear
what *kind* of USB device they are--and whether Linux and Xorg will
be able to drive them. It looks like there are something like
5 different types of `USB touchscreen' device that are explicitly
supported upstream, and I've found some mention of patches to
support other types--and by `types', it looks like I mean OEM
components, not branded devices that I can buy as a consumer.

Is anyone here familiar with using off-the-shelf touchscreens,
and able to make a recommendation as what particular devices are
most straight-forward to get working?
