being that this emulator works better on windows pc

ppsspp works great on a surface pro tablet(windows 8 pro, x64) with a USB controller.

on-screen analog works well, but on-screen buttons don't respond to tapping(siding/wiggling does work)
most likely because of how windows translates long-press to right-click, you'd probably need to use a metro interface to get touch controls working properly.

games play great, games that run choppy on a note 2 run at full speed(without frameskip!) on the surface pro.
and those games look amazing on a 10" fullHD screen, considering what they look like on a psp or vita screen.
several of the graphic glitches i've encountered on my note 2 don't occur on my surface, but there are still some games with glitches(like phantasy star portable 2, where some letters don't show right away and objects vanish when they're too far away)

my advice however: don't bother getting a windows tablet for anything less than €700{or $700 for americans) if you want to play games on ppsspp(or any games for that matter)
the surface pro is probably the cheapest windows 8 tablet that doesn't use an atom processor, and even though it plays everything at full speed it's clearly near the limits of what its little dual-core i5 can handle.
