In fairness, TVs have always been dogs. My old CRT TV back then would take about five seconds to show a picture and like 15 to get as clear and bright as it was supposed to be.
But yeah, when I fire up my old NES or Genesis, I'm struck by how much time modern systems waste with loading. I can already be through level 2 of Super Mario Bros. by the time Assassin's Creed III actually lets me start playing.
No OS bootup, no OS navigation menu, no game booting delays, no game level loading delays. All games, instantly.
Nowadays, even my television (Westinghouse 40") needs ten seconds from power-on to showing me a picture :(
