Marco Arment On The New MacBook Air
Insightful analysis by Arment:
The 11” looks impressively tiny, but realistically, most people are unlikely to see significant benefits in portability or practicality from the 11” over the 13”. There are very few situations in which you’d be able to comfortably carry or use the 11” but not the 13”.
The 11” screen resolution of 1366x768 is great for its size, but it’s going to bevery cramped, especially vertically. Screen size is very important and noticeable in everyday use, and it’s often the limiting factor for how much work advanced users can comfortably get done on a laptop.
The 11” is also significantly slower and with less battery life, although these are less important factors.
The whole post is a must-read. Although in my opinion, that 11-inch model is damn tempting.
