Could you carry this for me?
It's only small, it shouldn't take up much room; wait, have you checked you have the space? Do you need it for something else?
While I'm doubtful over the certainty as to which system is really 'perfect', since it does depend a lot on the game, I do think the future of Survival Horror, good Survival Horror, will in part be reliant upon games that consider the inventory system just as important a factor of a game's 'punch' as atmosphere or tension. After all, if a game makes you worry about whether you should lug the shotgun or the rifle around with you, because of how much space they each take up, then it's already a step ahead of the game that just lets you carry both, without worrying about it, in terms of crafting good horror, because it's already making you worry.
And if anything defines really good horror its being able to create tension and anxiety before you've even seen your first monster.
