Being quite the 'tech head', I own a portable gaming device or two, my weapon of choice at the moment being the Nintendo DS (When I can wrestle it from my girlfriend) it is quite simply a bundle of fun and the best device since the Sega Game Gear (I am that retro). The magical thing about the DS is a little device that allows you to play older games and so on. I wont mention it's name for fear of promoting a pro 'pirate' view of gaming but it allows for Snes and Megadrive emulators.
With this discovery my childhood memories have all come back, the simple tune of the opening of Sonic floods me with nostalgia, hours spent trying to get past the second level, trying not to stand on spikes and the explanation for my irrational fear of men with ginger moustaches. It is all here. Sonic quite simply is the platforming bomb.
