What about all those games that were designed for mouse speed and precision? I guess that mostly related to older games though, with modern AAA PC games tending to be much more pad friendly.
True, but while the Intel SoC is fast for a mobile CPU, it is still about as fast as PCs were 2008.
So you will mostly be playing a bit older titles.
Then just plug in a mouse?
Well, not very practical when sitting in a train.
Call to Power 2 is perfectly playable on the Pandora, e.g., but the buttons are too small to hit them properly with a capacitive screen.
About the touchscreen:
It doesn't make sense calling one superior over the other.
Both have advantages and disadvantages.
A capacitive one is more sensitive, but you can't use it with thin styluses.
The resistive one is more accurate here, works with any cheap stylus, but the picture quality is decreased (because of an additional foil).
A capacitive one has multitouch, but you can't use it in the rain (as any raindrop confuses the touch).
So there's no better or not better, there is only a better suited or not better suited one.
I think for PCs and desktop systems, a resistive is better suited, for mobile phones (which you often hold in one hand and only use one finger), capacitive ones are far superior.
For the Win? I would choose a resistive one, but they're harder to source, it's more work these days.
Yes, Win10 is touch optimized, but not most of the games / apps you want to run with.
But that's subjective. It doesn't make sense to say one is better than the other. If you want to compare them, you need to do it properly, objective.
Write down what's good and what's bad.
