There's so much range confusion over at Apple right now it's starting to feel like the 90's all over again.
Compare the Macbook with the 13" Macbook Pro, there's a ridiculous amount of overlap there that makes their pricing structure seem ridiculous.
Macbook Air has always been touted as " high end specs, flexibility all with great portability". The Pro was sold as the mobile beast. There's some range confusion it seems.
