Well I recently bought a Wandboard Quad (http://wandboard.org/) and have been moving over some of the things I use my Linode for such as remote desktop to it. So far it’s working really well. Even when I stressed it by doing a kernel compilation on all four of its cores it only reached about 50oC.
I’m also planning on using it as an always on desktop in my home as it’s currently connected to my TV and when idle consumes about 3w.
So watch this space for updates and I’ll also link to some notes on my wiki about getting various things working when I figure them out myself. Unfortunately the Wandboard is not as well documented as other boards such as the Raspberry PI and Beaglebone black.
