As documented in the past, it seems like the internal architecture of the Xbox 360 is just prone to overheating, so in order to prevent that from happening, the new "Xbox 360 Slim" will just make you wait for a few minutes until the power light stops flashing. We understand the fact that this could serve as a hindrance during your "epic gameplay moment," but if you ask us, it's better to give your Xbox 360 a 5-10 minutes break instead of waiting a month for a replacement or fix.
So unless, the OP Father has the money to plonk for a 250GB version 360S, I'm not sure why he would upgrade.
