The Daily Grind: What bonuses do you want from a collector's edition?

I did something with Final Fantasy XIV that I've never done before -- I purchased the collector's edition. Normally, my love of in-game pets and art books is counterbalanced by my love of saving $25, but an extra eight days of playtime is fairly non-negotiable for me. Everything else that comes with the collector's edition is a nice side perk, but nothing worthy of the extra expense in and of itself.

Of course, there's no shortage of players who consider the additional cost of a collector's edition well worth some in-game vanity pets and an art book. For some, simply having something labeled as a collector's edition is justification enough, as it signals some sort of elite status as a player. What sort of things make you interested in a collector's edition of a game? Do you prefer in-game benefits to display to other players, or trinkets for fond reminiscence? Or are you mostly motivated by games that give you an early start or something similar?
