Interesting. Can you give more details on your work? I've been on the edge lately over picking a desktop, an intel NUC or something like a Pi. Price to performance and power draw is something I'm considering.
Same here. A great advantage of such devices is they can later be easily repurposed to control home automation, audio system or make a simple DIY project with them. It is much harder with other types of hardware, like a laptop for example.
I use them for development. One has ubuntu installed and the other Fedora.
