Hm, but that kind of display will need additional drivers and integration with Reaper. And the price + shipping cost + time needed to make it work is almost on par with decent used notebook or 1/2 cost of 10" touchscreen which works out of the box.
I have that stand:

I can mount to it wide array of add-ons, for notebook, iPad or even for sheet music. It should be no problem at all to mount 10" screen... or OLED
. I wear glasses for quite some time and tiny screens are no-go for me, even the best ones.
