Does the firmware matter after it's been hacked? Do older firmwares like 4.1 offer more than 4.3? After hearing about letterbomb I'm getting a wii, but if the wii is below 4.3, what's stopping anyone from just staying up to date? tl;dr - Do firmwares 4.0/4.1/4.2 etc offer something that 4.3 doesn't? Off topic. Why not stay up to date? Thanks!
