Forgive me if this has been a pre-discussed topic (I searched and couldn't find anything). I was wondering what the rest of the kind folks of MR did in relation to getting your Macbook Air's with 4GB of RAM? I am buying one for my girlfriend for Christmas (I'm a MBP man myself) and I am wanting to get the base 13" model but with 4GB of RAM so she can properly do HD video, run VMWare if need be, etc. Of course you buy from Apple and customize but the end result is a $100 more charge than buying it from Amazon (through OnSale reseller) or MacMall. I would love to save $100 bucks of course, so I was wondering if any of you knew of alternative places to buy the MBA? I am a little wary of buying through Amazon because it is not sold directly by Amazon (it is sold via OnSale) and MacMall I have read horror stories on misregistering of serials, cheap RAM, poor shipping/customer service, etc. Did all of you that got 4GB MBA's just buy through Apple and pay the extra 100+ bucks? Thanks for the advice!
