Just some additional info on the Intel NUC, I've been doing some hands and feet installation work with the NUC's for Internet Kiosk applications in department stores. They can have an internal wifi board or use an external USB wifi dongle, keyboard and mouse of course just run via USB, Video is via HDMI (2 ports are available for dual screens). My understanding is that the only Disk option is SSD. They are now also available in an i5 variant, but like the i3 they are sold without RAM and SSD. With a suitable illuminated keyboard and a couple of screens they would make a nice alternative to a laptop for field work. The ones I've been working with are running win 7 quite happily, although there have been some problems with the USB wireless not initialising properly on bootup ( 8 suspect this is a driver issue).
