Hmmm, considering a vast portion of those apps are crap, or simple little games that you play for 2 days then get bored of, I would actually call it the 'crap' store.
Say 90% of them are crap... That still gives you 10k more apps on the iPad that are quality or useful over anyone else.
By the way it is not like the android marketplace for phones has some kind of higher quality ratio than the app store. In fact some people would say that the overall quality of apps in the android marketplace is worse than the app store.
So having lower quality apps and a tiny fraction to boot.. well it is not even a reasonable discussion to have.
