<br /><br />
There was two options that I had got quite interested in. One was the Nvidia Tegra based Jetson system modules, and there is a graph database application called Blazegraph that can use OpenCL to accelerate walking database graphs for searches. This probably applies then to any device with OpenCL capability, which brings me to the second one, which I have decided to take the plunge and get into.
<br /><br />
It's the Asus Tinkerboard, it has a quad core 1.8ghz ARM processor, 2gb of ram and a fast SDXC UHS-1 interface for its primary storage. Supposedly it can drive a 4k display and decode video, which is kinda amazing to me. But I'll be fine with it doing 1080p perfectly. I am getting one with a standard 800x600 8" raspberry pi touchscreen display, which means I can experiment with touch interfaces as well.
<br /><br />
The primary concern about it is that it is usable for basic web/media purposes, and that it is ARM, really. I have been itching to get into doing arm development but the lack of fast enough devices, and circumstances, has held me back, but this new little offering from ASUS, who is also my  favourite hardware maker, I must have this and make it my servant :)
