Right i need some opinions from some fellow mac geeks! I currently have a mid 2010 i7 iMac as my main machine at home. However I have recently landed a new job (YAY go me) Where ill be managing the company's Ad Ops, Social Media & Email Marketing. The job is in London, eventually I plan on moving there. So thinking of swapping in my iMac for a laptop. But I cant decide which one!!! The work ill be doing will be using a lot of online web tools, with a little bit of coding, photoshop and of course email and documents. My worry is that ill struggle from going from a 27" screen to a 13 / 15 " screen. As i like my screen real estate! I have put together a numbers doc, screen shot attached of the specs im after. Has anyone else downsized and are very happy. Eventually ill look to get an external screen, but for the time being ill be using a laptop at home and in the office. So far with my investigations, I have come up with. Do i want to sacrifice screen res for battery power? With the MBA having a higher bench than the i5 retina I wouldn't really be losing power. Its only when i upgrade to i7 that i see the benefit of a faster machine AND better screen res, but then its almost £300 more... Thoughts?
