Is it weird for me to want a family of PSP’s?

I mean, between me and my girlfriend, we already have two, a launch piano black and an imported pink. Then, last week she tells me that she no longer likes the pink one and thinks that we should get the Slim & Lites. Black ones, since the other colors seem kind of cheap. (Plus, I’m not sure I want a Darth Vader imprinted forever onto the back of my PSP) I like all of the new and improved features, but for some reason, I don’t want to just have my old PSP put out into the wild if I trade it in.

On the other hand, if I keep all of the PSP’s and end up with four, what the heck am I going to do with them? Is there anything I can do with them? When are they going to firmware in some features for the ridiculously rich, or the hopelessly sentimental people, who are going to end up with these families of PSP’s?

By the way, has anyone seen these Slim & Lite Core Packs out in the wild?
