Discussion question - what incentives need to change to make Apple invest more in Safari? They've always been invested in native apps first and foremost, because that's where they make their money - the app stores.
The other place they make their money is hardware. And it's hard to say you buy a MacBook or iPhone because of safari. You don't.
So I just don't know what it will take for Apple to make significant investments in the web. Whereas Google makes all their money on the web.
