Greetings everyone, I have a question that I am sure that a lot people have asked themselves lately. I currently have a 15'' MBP i7 Quad Core processor. I primarily use the computer to run GNS3, which is a pretty CPU intensive emulation program used to emulate Cisco Routers, checking email, surfing the web, and listening to music. Even though my MBP is fairly new, I travel a good bit and a little computer would be awesome. My question is, is the 15'' MBP Quad Core i7 that much powerful than a 13'' i7MBA and will the MBA be able to handle a cpu intensive program such as GNS3? If so, I am going to sell my 15'' and get a 13'' MBA today! Thanks for any insight on this!
