Going by respective console generations -
SEGA Mega Drive/Genesis > PlayStation > PC
Game Boy Color > Game Boy Advance > PlayStation Portable > Nintendo 3DS
PC (gaming).. I started during PS1 era and has been a staple of gaming alongside consoles. Its probably been my primary platform since the PS2 onward if not earlier. If we are talking just consoles PlayStation has been pretty much my go-to with the 360 nearly dethroning the PS3 in the 7th gen.
