I wouldn’t be so eager to get a x5-z8300 Cherry Trail tablet. The z3736F will actually outperform the low-end cherry trail chipset while running at much cooler temperatures. The atom z3736F chipset is currently the fastest at the $100 price range. Also keep in mind the Hi8 Pro will be single-OS Windows only, and whether Android can be installed onto it is unknown.
If I were you, I’d look for a z3736F tablet with a 2MP front camera. (The front camera on the Chuwi Hi8 is pretty bad.)
