Face it, if the ipad can't function with one of the biggest, most popular websites on the web, that's a glaring hole. Facebook was around a lot longer before ipad.
I have a Facebook app on my iphone that works fine.
I can easily browse FB on my iphone as well. I think a lot of people access FB to "speak" with friends and not just play flash games...
Frankly if this kills FB gams then maybe Jobs is doing us a favour
