Intel is open to sell the 65-nanometer Core 2 Duo processor that it customized for Apple for use in its MacBook Air. In fact, it is known that two PC manufacturers, Fujitsu and Lenovo, have already signed on to use this chip, and products powered by it are expected to be out in the market shortly.
The thinness of the notebook was achieved in part by a miniaturized 65-nanometer Core 2 Duo processor that came from Intel's older Merom line. The processor is 60% smaller than the typical Merom chip and uses less power while delivering comparable speeds. The processor, however, is significantly slower than the latest Intel Core 2 Duo processors used in other new notebooks. Performance is not necessarily an issue with Apple as it customizes its operating system to maximize performance out of any processor it uses.
I personally use a Sony Vaio TZ laptop at the moment. I value its good battery life (5-6 hours "normal usage") and compact size that somehow manages to squeeze in a DVD-Writer and a full complement of ports.
What would you go for -- the MacBook Air, with its minimalistic style, or do you prefer something like the Vaio TZ?
