Hi, I am about to finally kick Windows to the curb and switch to Mac, and I've been waiting for MWSF hopefully waiting for some type of MacBook update. The Air is pretty neat and all, but it doesn't meet my needs as a desktop replacement. The only thing I really envy about the MBA is the LED back-lit screen. For anyone who has any info or has seen the MBA in person, is there a significant difference between the MacBook screens and a LED screen? I plan on using the laptop for a long time and I don't want to get left with an archaic screen. Thanks
