Oh, I don't know yet. The remarkable does what it advertised for now, and I'm happy with such a basic usage.
However, if the company goes belly-up, if it stops supporting my device, if I get creative one day and have this awesome idea, I can implement it.
Of course, the Android ecosystem is quite open already, so this is a step-up from, say, a kindle. But having root access feels more like having the keys than sitting in a cab.
An idea I had for a while: draw simple schematics with the stylus, simulate them on the tablet with some SPICE implementation. Shouldn't be that complex :)
I am aware that the developer ecosystem around RM devices is top notch, however I had different needs from my device. To each their own.
