I was holding off on getting the 13" MBA for the new Retina MacBook, but now it looks like I'm unsure of which route to go with. I already have a 27" iMac at home that I use for everything. My main decision to get a laptop was for portability. I will be using the laptop for the typical/casual stuff, such as surfing internet, facebook, email, youtube, imessage, facetime, google hangouts, skype, etc. With some occasional graphic design work using photoshop/illustrator/indesign, and iWork, MS Office, and photo editing work as well. Will the new Retina MacBook work well for this compared to the MBA? I'm not familiar with the new Intel Core M chips and Intel HD 5300 vs the i5/i7 and Intel HD 6000 in the MBA. Overall, which one will perform better and if so, will it be a much noticeable difference? I really like the retina screen and size and looks of the new MacBook, and that's my number reason to get it, for portability. Would like to hear your thoughts and opinions for those of you who face a similar situation as me and can't decide on which to get.
