There are way too many books for getting a library card to make sense!
Bad analogy. If one already knows how to read, then selecting books, either specifically or generically, which intrigue one isn't an insurmountable hassle. Choosing apps, many of which are arcane, is a whole nother kettle of fish.
As an aside: I don't even know and haven't bothered to investigate all the apps which came with my iMac running Lion. From all I can tell, it'd take years to figure how to work them. I ain't interested in wasting my time like that.
