I bought a OneMix 3 Pro to replace my Venue8Pro.
Could never get the pen to work very good on it.
Dell sent me 3 or 4 pens to try. But the squiggles were too great.
I gave it to one of my nephews. He still has it. He mainly uses it for reading eBooks, so doesn’t use the pen very much.
The OneMix 3 replaced it.
It has an I5 processor with Windows 10
The screen is 8.5" and flops clear around to use as a tablet.
It has an NTrig digitizer screen with touch. It is somewhat wonky for graphics editing though. Better than the Dell pen, but not as great as the Wacom pen. Works great for pointing and clicking though.
But it has a full size USB port as well as a USB3 port, plus a Micro
USB
Biggest problem is heat. Boy, does this thing get toasty on the bottom if you are pushing it. The fan is noticable. Just reading or typing, it is quiet and does not get hot.
The case is aluminum as opposed to the Dell plastic.
I like it for light computing as it has the built in keyboard to protect the screen.
It is roughly 5.5 " x 8". About the same size as the Venue8Pro.
