PS has made lots of improvements on the front of being more mobile-friendly imo. I got Showdown to work on a second-generation iPod Touch (though I very rarely use it, as I have both a tablet and a computer to use). This should be a testament to its user-friendly-ness. It is however optimal (as a temporary solution until the mobile version is no doubt improved, as the xf team is working on it) that there be some sort of toggle switch between the mobile and desktop versions instead of the code just automatically detecting your hardware and picking the version for you. It should do that on default, but there currently isn't an option to opt out of said. I don't see why there can't be a toggle to mobile in the desktop version either, despite how useless it might be.
