Odd. I thought Android supported Ext4 as well. A few years back they wanted to remove it (why??) but public outcry changed their minds. Did they sneak this anti-feature back in, with a newer Android feature?

What's keeping me from ordering a device like the Gemini or GDP Pocket 2 is the apparent lack of an accurate point device, like a trackpoint or induction stylus. These device are more suitable to run desktop apps on occasion than smartphone, but hitting on-screen buttons with your fat fingers might be too cumbersome.
Or am I wrong on this, and is there a solution for this? (apart from linking up some external BT pointing device)
