Hello, this is my first thread here. I'm planning to purchase a notebook, but I don't know MBP or MBA which should i buy. With my new macbook, i only use safari, iTunes, email, office, and other applications for work and study , i don't going to play games on it. And i don't use the optical drive (there is a optical drive on my current notebook , but i have used it less than three times in the past 3 years). But i heard that Macbook Air is a "crippled" notebook. so i don't know if MBA is really "crippled" compared to MBP. In my condition, which do you think i should buy? thanks in advance.
