Hi,
to get it easy there are 04 versions of HI12, but there is no difference on the screen as there are all equiped with the surface pro 3 screen:
- windows only with processor z8300
- dual boot with processor z8300
- dual boot with processor z8350
- and the last one (batch from xxxx042017xxxx) is dual boot with processor z8350 equiped with the same digitizer as the HI13 (compatible with the stylus Hipen H3 which is more accurate and support 1024 pressure level).
I Hope it is more clear now, of course if you want to buy one you need to wait a little bit to be sure to receive a tablet from the last batch.
Best regards
