By the way, I recommend the Winbook tablets (7, 8 or 10 in.) available at MicroCenter for less than $100. They have a full size USB port for the Ross Tech adapter.
Although I used the free upgrade for Win10 from Win8, it used up quite a bit of space on the 32 GB SS drive.
After a year I did a clean reset/install (removes all files) to Win10 and tablet works great, also with VCDS.
