Im sending out my last student loan payment at the end of January, so I thought Id treat myself to a new Macbook in early February. I haven't kept up with new mac models for a few years so I'm trying to do my research. I need something for Web surfing, e-mail, media, and running office productivity software. It would be used as my home and work computer. So lightweight mobility is a plus. Right now, I use a first generation Core duo MacBook Pro from 2006. It is my main computer. My only complaints about the machine are that the battery life is atrocious, and the heat that is generated by the CPU can get rather uncomfortable. That said, Im having difficulty choosing between a MBA or a non-retina display MBP. Im definitely leaning towards the MBA but there two things that bother me: the lack of a built in optical drive and no Ethernet port. The thing is, Im not necessarily sure how much I would miss these things. Ive never used a computer without them, but at the same time I dont find myself using the optical drive that often anymore. I havent burned a CD or DVD in years but I do occasionally watch DVDs while travelling. I also rarely use the Ethernet port. So would you guys recommend the MacBook Air as a suitable replacement? How has the MBA worked out for you? Also, how is the battery life and what is the situation with heat generated by the MBA, and MBP respectively?
