We have looked at two machines. The Fit PC and the Fit PC2. Both were for
small deployments (<25 units).
The Fit PC:
500MHz Geode, with 512MB RAM. Full specs at
Power consumption at the AC/DC powerbrick = 8W
Stays warm to the touch (104 F in 72 F ambient temp)
We replaced the factory installed drive with a 64GB SSD.
The Fit PC2:
1.6 GHz Atom, 1GB DDR2 RAM, 6 ports, etc. Full specs at
Power consumption at the AC/DC powerbrick = 15W
Gets hot to the touch.
We've installed XS 0.6 on both machines successfully. The FitPC2 does have
some reboot issues (hangs) so we didn't send it to Madagascar. We have the
FitPC in the field in Maroantsetra, Madagascar, but isn't being used much
due to other issues (lack of tech expertise in the field). We'll know more
about the behavior of these once Ben (cc'd) has had a run of tests on these
machines later this month.
