Chances are, most developers they are targeting are on Macs, so they made it easy for them.
I already know what I want to watch so iTunes is good enough. But maybe it's just me.
But happy watching. It's a great resource, every year.
It's fine, I'm barking up the wrong tree here TBH. Apple makes it clear that they want you to use their products to view this developer stuff. It's the same type of lock-in that others try to do, so they're not the only guilty party. Just unfortunate when companies do that.
I'll go and install iTunes.
It's also probably more convenient to them: they have this huge system for content delivery through iTunes, so they might as well use it.
That said, from a promotional aspect, it would make more sense to have the videos readily available for Windows/Linux users also, so they can lust over the development options for Cocoa/iOS.
It's not like they wont have to buy a Mac to program for it anyway, so it would do Apple no harm to lure them with openly available videos.
