I have been doing the same with all my (30) games too. Was playing Resident Evil 2 last night, wide, with headphones in a dim room. So good.
Overall the wide/stretched function is pretty much the only way I will play them now, aspect ratio be damned. On PSP I didn't stretch. On PS3 I didn't stretch. But on the Vita it looks fantastic, and you forget about any kind of squishing very quickly. I would recommend those who think it's blasphemous for others to enjoy it stretched to at least give it a shot on the OLED. Personally playing my games at the normal, or original settings feels neutered in comparison.
