I, umm, impulse bought this. The ARM ones had little appeal to me other than the form factor as I have several ARM computers already. But, a reasonably priced RISC-V machine and a cool form factor? Yes please. Without a GPU it will be a text based machine, similar to the TRS-80 from which it draws inspiration, but it should be more than sufficient for SSH and telnet.
EDIT: This chip is beefier than I thought it would be. I had multiple comments on this, and finally found the datasheet from Allwinner and what follows is what I found.
**Allwinner D1 SOC facts in brief:**
* XuanTie C906 RISC-V CPU and HiFi4 DSP
* DDR2/DDR3 SDRAM
* SD3.0/SDIO3.0/eMMC5.0
* H.265/H.264/MPEG-1/2/4/JPEG/VC1 decoding, up to 4K

Still waiting for mine :( I hope they manage to get these out.
$100 cheaper then the A06 model I have on order.
Would you recommend going with the RISC-V model instead? (Might be more fun.)
It finally showed up. I did a review:
