This. I actually fell for the UMPC meme back in the day, and the number of PC games I could play without at least intermittent keyboard use was far smaller than I realized, even with a touchscreen, stylus and physical buttons.
For those few older PC games you actually can play without a keyboard, though, one viable alternative is emulators. Most modern cellphones can run DOSbox (DOS or Win 3.1) at full speed, and some of the latest flagship phones can even get QEMU (Win 9x & XP) running at around the speed of a Pentium II.
