hiya guys, So im planning on purchasing a new mac very soon. I ideally want something powerful yet I also want something very portable. I am a web designer so I dont demand 8 cores etc but I do want something that will definitely last. Im am now deabting... either a top spec iMac and also a macbook air... or a top spec macbook pro with a 24" acd. From what I have read I assume that the top spec IMAC's parts are similar to the macbook pro and so therefore I am assuming that it will be more powerful? So i feel it would be more beneficial to have the imac with the air. Also this riduces risk of not having a working computer but also having a fully portable machine, as when portable I wont be doing much of my work. What do you guys think? Am I ring in thinking the MBP is not a lot more powerful than the imac?
