Well, the Skype app is even worse on a surface pro 3, in tablet mode and HDPI screen. I refuse to use it, app does not scale on HDPI screen, and as such looks dreadful, and with the old style notifications (the slide-in boxes from the lower right on the screen), in tablet mode it's just disastrous. Plus, as the app minimizes when you close it, in tablet mode it just does not close (if you try to slide down or app-switch and close it). So, good luck using it on a tablet. And again, this is what a new user will experience this Wednesday. At least until MS releases the new chat app, whenever that might be.
