Oh dear god no! Please! I'd rather use a Mac!
Not so fast. These little bastards can be amazingly useful. If you can manage to use a Gnu/Linux box, you can use a Raspberry PI 3 as a (very) capable Graphic terminal for your cloud appliances without worries.
I'm using a bunch of crap, I mean, Raspberry Pi Models B (that one with 512Mb) in a little cluster for miscellaneous tasks, and the damned things work fine. I built a web radio for my home with two of them, and they still have a lot of juice to spare.
Banana Pi and Orange Pi are also capable machines, but lack the support Raspberry Pi has. But other than that, there's some interesting applications for a small computer (smaller than a 3.5" sata HD") with sata ports.
