Somewhere near the avg. with 66 apps.
But most of them are just there taking up space. So far I haven't found many apps that I use regularly apart from IM+ and Safari.
There are many apps which are good at what they do, but it is getting tiresome to have to switch to another app just to use it. I am hoping that Apple with release an iPad with Mac OS X Lion later this year and abandon their forced fullscreen policy.
