Android update 2.2 to 4.0

Hy all, i bought a mid tablet from eurodualsim and after i used it for almost a full year, it's a wm8650 model with 800mhz processor and with an os 2.2 google android and although i'm very pleased with my tablet i want to make an update to 4.0. I read on google blog what benefits brings this update and i want it too, i don't think i'll ever use them but as new stuff fan i want this and i want it bad. So i want to ask you guys, is this worth it? It bring is more fun stuff than google said?:confused: kudos;)
