ExtremeTech reviewed the new Fit-PC Slim.
Conclusion:
CompuLabs really needs to step up to a more modern platform if it wants to stay competitive in the rapidly growing market for small, net-top PCs.
They missed the point. It's not a "net-top" or desktop replacement, it's an extremely low wattage home server.
The spec that matters:
Power consumption: 4-6W
Compare that to the 50-100w of typical desktops that are used as home servers & left running 24 hours per day, or the 20+ watts of a typical notebook. Even an Eee PC uses 15 watts.
If what you need is a home server to use as a samba share, a web server or similar always-on device, a 5 watt brick looks pretty interesting. That's 500kwh/yr less power, 400kg less CO2, and $50 less on your electric bill per year than the old desktop-turned-server that you have stuffed under your desk.
And don't whine about the 500mhz processor and 500mb RAM. We ran LAMP stacks that served up more users than your house ever will on a quarter of that.
