Hi all, I've had my iMac for a long time now and could do with something a little more portable. I've been looking into getting an ultraportable like the Macbook Air, but have recently got interested in some of the new generation of ultrabooks that have just/ are about to come out. Does anyone have any thoughts on what is the best option, in terms of value/ overall hardware specs/ longevity/ OS/ usefulness/ anything else? Of course I realise this is the MacRumours forum so if you're reading this you probably have a bit of a soft spot for most things Apple, but I was hoping to maintain a little bit of objectivity. Basically what I'm looking for is something up to the price of the 13" MBA. Portable as possible, high spec, nice screen etc. I'm also considering the MBP, but it is somewhat heavier. I live in the UK so prices aren't directly comparable to the US (sadly), but am still a student and am able to get a discount for the time being. Thanks!
