Mini PCs vs tablets - do you get value for money?

So far the new Cherry Trail mini PCs are all pre-release or crowd-funded so in comparing specification versus price I thought it would be interesting to look at the ASUS Transformer Book T100HA.

You get an x5 Z8500 CPU, 4GB RAM, 64 GB eMMC, 2.4/5.0 GHz Wifi, 4.0 BT, 1xType-C USB 3.1 (5Gbps), 1xMicro 2.0, 1xMicro HDMI, Windows 10 plus a screen, a keyboard, a battery, a couple of cameras etc. all for $299 and available now.

I've already mentioned the convergence of mini PCs with barebone devices and now it seems similar for notebooks/tablets. Effectively suggesting that mini PCs are becoming over-priced.
