Guys, Have been using this site for a while now but never really had the need to post anything but am facing a small dilemma which I would appreciate your feedback. I currently using a white late 2007 MB and am contemplating getting a new MBA 13". The MB is working fine, I've upgraded the RAM and the HDD and the only problem now is the temperamental back light on the screen which turns off at certain angles. The reason that I am thinking of upgrading it because I am planning a trip to the US (I'm from London, UK) in mid-May and checking out the prices in the US vs UK, I would be saving over $450 on the top spec MBA but then I have been hearing about the new Ivy Bridge processors and the improved speed and efficiency, but sadly no idea of release dates (but assuming it will be after my trip). So my dilemma is whether to purchase the current one and pocket the savings or wait for the new MBA with the new processors and pay the extra GBP? Having said that I probably wouldn't buy until later if I do get it in the UK as the MB is still running fine, but I guess the attraction is the savings I'll be making knowing that I probably will be upgrading in the next year or two. A couple of questions also is does the MBA get hot with prolong use? My MB gets pretty hot over time and so I'd be glad for a cooler running machine. Also, whats the likelihood of the 256GB HD being increased with the new MBA? Thanks.
