I recently purchased a MBA 13' 4GB ram, 256GB storage to return it in fifteen minuted for the rMBP 8GB 256 GB. I love the retina display of the pro but I also shyed away from the Air because I thought it was going to be an underpowered, slow computer from reading the specs. The price difference is several hundred dollars between the two and I am unsure as to why if it really was worth to get the air after seen that most people have no problems with the air. I have spent hours researching on google but still am not sure: I am a grad student so most of my time I will be writing, creating presentations and using the internet. Non-school wise I'd like to watch movies, listen to music, maybe occasionally do photo shop, open many tabs in browser and have maybe 5-7 programs/files open at once. I also like the play games on yahoo or MSN. Is a Macbook pro overkill? What type of people benefit from a MacBook Pro?MacBook Air? I like retina but that won't be my sole reason for picking which computer I want before the return date. A sluggish computer or a computer that will get sluggish overtime is not something that I want. Thanks!
