Anyway, I think plenty of people were fine with the OpenPandora's mega tiny 4.3 inch screen and fans of that machine seem happy that the Pyra will have a bigger 5 inch 720p screen, so there's that.
Well, yes, but it always depends on what you plan doing with those.
The Pandora worked fine as it was mostly used for older games which didn't use high resolutions and had larger text.
But one issue was that it was only 800x480 and many many later PC games were made for 800x600, this made porting really hard.
For 720p, 4,3" is just too small - I was happy to be able to use a 5" display without having to increase the size of the unit itself.
For Windows however, it's totally different.
For playing older DOS and Windows games, Windows 10 is not much more useful than any Linux as you need to use something like DOSBox anyways and older games often work better using WINE than on Windows 10 (except if you use a virtual machine, of course).
Windows however gets cluttered easily if you often install and deinstall stuff - on Linux, clearing the WINE directory gets rid of everything without a full reinstall
Newer games are made for 17" and higher, so here the 5,5" screen is too tiny.
We'll see how this will all work out, of course, but right now, these are some of my concernts.
