Win32 apps suck at touch and always have. MS has had pen and then touch devices out via OEMs for over a decade. Trying to close a browser window via a 16px &quot;x&quot; is terrible on a 12&quot; laptop; but on a phone?<p>Your phone running full Win32 APIs probably isn&#x27;t the great boon it&#x27;d otherwise be. Likewise Windows tablets have not gotten much traction in the past (or present) -- you simply must have a pen and most likely a Bluetooth keyboard to properly use them. I bought a few, tried to use them, gave them to people -- Android devices just blow them away.<p>The real touch apps --- Metro -- are pretty terrible (slow, even MS&#x27;s own Metro calc takes seconds to load.) And of course mean rewriting a lot of things.
