So I had a NUC lying around, just one with the Celeron chip so it was never going to fly me to the moon, and I decided to put Lakka on it. Have to say it's not bad.
It's great to be able to play all the old Atari games I grew up with (that I still have the cartridges for, of course) - River Raid, Space Invaders etc, plus some of the later Playstation games like Driver 2, GT2, Spyro (for the kids) and Sega games like Sonic, Sega Rally...
Purchased a couple of Dualshock 3 controllers to go with it (cheapies off eBay). For the cost and form factor it's not a bad little machine to start the kids off (and maybe myself as well :-) )
Plenty of fun to be had from a time when gaming was a little more "fun".
