I was thinking of buying the x80 power, at the end i bought the iwork8 air (it has remix os port and cyanogenmod 12.1) and less problems than the x80 line.
Dude, Teclast-tablet is not teclast official shop, is just someone that adquired the domain and started selling teclast products, there is also cube-tablet, onda-tablet, etc. All of them are not official stores.
The teclast x3 pro matches everything (8 gb ram, active stylus, also 128 gb SSD, Core M3, etc) and the keyboard doesn’t use a kickstand (its fixed possition tho). And the bad thing is that it is priced at around ~450USD (although not as pricey as a surface).
