It's strange that you would argue that "console games do like their games more simplistic, casual, and streamlined. It is simply the nature of the console that allows for the gamer to be less attentive to details" being that a limited save system is pretty much the opposite of that. A limited save system requires more work from the player, because it means they need to be more attentive, so they don't lose all the work they've done before getting to the next checkpoint/safe zone. By allowing the player to save anywhere you remove this, making it easier from them, and as such it's the save anywhere system that's "dumbed down".
Take Far Cry 2, for example. The console version only allows you to say in specific safe zones, while the PC version features save anywhere. The developers didn't exclude that feature from the console version because "console kiddies" just luurve a limited save system, they included it in the PC version because PC gamers bitch when they don't have it.
