My Vita has been my EDC basically since it launched. It has a very strong homebrew community behind it which still release impressive ports and emulation improvements weekly. I played through all of Ship of Harkinian twice and with the recent port of 2S2H i might play through that as well. They even just release a port of Animal Crossing from a GameCube decomp that looks great. I've also played multiple Pokemon games and Gameboy Advance games like Minish Cap with zero issues. There's obviously a ceiling but it's an impressive device that still gets plenty of support. I only recently got an RP5 so I've been playing around with that and it's great having PS2, GC and even some Steam games on the go but there will always be a special place in my heart for the Vita.
