In Defense of the Positive
In defense of the "Positive"; seeing there were (at the time of this posting) 1893 Negatives and 488 Positives attached to this topic, I felt I would present another Positive.
The first thing that occurred to me, in regard to the new MacBook release, was that somebody was filling a demographic marketing hole/vacancy.
As far as "Santa Rosa", 'everybody's got that'... but,
I get the impression Apple, as usual, may be a little 'further ahead' than credit given and here is why.
I recalled reading 'a few things that stuck' from Intel's press releases and went running over there to dig them up, so I could present my case.
Keyword is: Penryn

Before piecing together my view, I thought I would take a look around to see if 'somebody else', 'was thinking the same thing' and came across this:
April 16, 2007: Intel offers a look beyond Santa Rosa - At Spring IDF Intel shows off a laptop running the Penryn mobile due later this year
http://www.infoworld.com/article/07/04/16/HNintelbeyondsantarosa_1.html
Which offered some interesting quotes and covered what I was going to offer:
"We will be able to take Penryn, the 45-nanometer [chip], and plug it into exactly the same platform to enable a fast ramp," said Mooly Eden, vice president and general manager of Intel's mobile platform group
"some gamers and hardcore users will want to push their systems past the performance limits set by Intel"
"Intel is preparing a mobile chip for gamers that allows overclocking."
"We've opened the design in such a way that you can overclock, but it's your responsibility to take care of cooling on your own," - Mooly Eden
"One possibility is the release of a quad-core chip on a single silicon die -- something that Intel has hinted will come in the future, but has so far not discussed in concrete product terms."
In closing, (imo) the MacBooks were a 'niche fill' and the near future looks promising...
