This make sometimes difficult to understand when they truly innovate.
(The Powermac G4 at 400Mhz was supposed to be a “super computer”)
Anyways as long as Webkit is gaining users, it will also benefit to Firefox and Opera (and vice-versa).
Dashboard and Spaces, for instance, both excited me a lot when I first got to use them, and in Space's case when they first got announced. I'd been using Ubuntu at the time, and I had both widgets and multiple desktops, but it was different. With the Apple system, it feels right visually and in effect. The way widgets spin around when you use them, the small thing like the clock turning into a calendar when you click it, in Dashboard. With Spaces, the way your windows visually flew around, and the way you could zoom out and see the little cubbies.
I'll get flack for saying it, but it just happened with Safari 4 and tabs. For the first time, they make sense where they are. I run Safari with minimal chrome, and now the tabs ARE the window bar. And that makes sense! These tabs are effectively multiple windows stacked into a single space. It suddenly fits perfectly how they're displayed. Safari 4 has problems with the specifics of how the tabs go, but for the first time it makes sense where they appear visually.
That's why I love Apple's marketing: because it's so excitingly arrogant. No matter what they've got, they talk about it like it's magic and new, and I love that in commercials. No people going "Oh! This is so exciting to me!". They just take it for granted that you'd better like what they're talking about. It's more fun to see commercials like that. (I adore the iPhone app ads, with the "Things have changed forever" slogan, for that particular reason.)
