We’re not entirely sure what this has to do with news about phones, but PhoneNews seems to have managed a bit of inside info with regards to an upcoming MacBook Air revision that many have seen coming for a while now. According to the rumors, the external design to the ultra-slim lappy will not undergo much of a makeover if any (and why would it?). The guts however, are seemingly in for a good upgrade. Starting things off, the custom Core 2 Duo will be bumped up to a Penryn-class Core 2 Duo and a bigger battery will be feeding it juice. The new model will ship with a 60W power adapter to compensate. The standard hard drive version looks like it will be available in two sizes, 120 GB and 180 GB, but there is no word on the capacity of the revised SSD version though the pricing will likely be in the same ballpark as the current version. According to the article, Apple resellers have already been notified of the impending upgrade which means we could be seeing it hit the market fairly soon.
