I jumped on PC after having numerous issues with 360, I've always played games on PC but now I pretty much stick to it unless it's some sort of exclusive or party sorta game: Playstation All-Stars Wii sports etc. But even then there's a number of multiplayer games that are now on PC and given there's a wider range of controller support on PC that makes that easier than the consoles currently here.
That said nothing beats the feel of a actual Genesis,PSOne, SNES with the actual system.
Handhelds: Vita, PSP, GBA-SP+ all get equal love, because they all rock.
