Okay, now that some time has passed, I've absorbed information from the media event, Apple web sites, etc, and can now offer up some more thoughts.
Yawn.
Yep, that's it. Okay, don't get me wrong, the MacBooks are the nicest/hottest notebook computers on the market. And that's whether you run Mac OS X, Winblows or both. The new gorgeous screens, zippy graphics cards, mongo trackpad, faster system bus, lighter/stronger form factor, et al, are nice. If you're in the market for a new notebook, you'd be mistaken not to buy one of these.
BUT.
As an existing MBP user (and Apple Fanboy), I'm really disappointed. There's really nothing in this product refresh that's really all that compelling or innovative. I think Apple played it WAY too safe. They should have blown people out of the water with a touch screen or integrated back scratcher or both. C'mon Apple, you let HP come out with a touch screen desktop? HP? And you know they have a notebook in the works (Update: Yep).
Why a touch screen? I dare anyone that owns an iPhone to tell me they haven't tried to touch a button in a dialog box on their notebook to clear it. It's a natural progression from the current input methods. Yeah, the big glass trackpad is nice, and certainly has utility, but BORING. I'm sure Apple is working on it, and whatever they come up with blow away anything HP or Microsoft or anyone else can do. But they need to step on the gas. As they pointed out in their own media event, they have a window of opportunity here to capitalize and they're going to squander it by playing too safe.
And yes, the manufacturing process and benefits of the new MacBooks are interesting, but John Q. Public could really give a rat's ass. They want sexy looking computers which work at a nice price point. The geeks love that stuff, but the new Mac buyers don't care.
BTW - Engadget has posted a nice list of various resources to get information about the new MacBooks.
