I know it has been asked before but now I have finally decided rev Bit will be only is it worth $600 for the 1.8 SSD? Is it better to save the money for the next revision or make this one last longer (at least a year maybe)? My take is that the SDD makes people feel they have a much faster machine, Is this correct and does SSD also provide less heat than the HDD? Battery I understand is about the same, right? Sorry for asking what has been discussed before but my thinking is that there are finally more HDD MBAs out there for comparison so it should be a good time to ask the question again. Thanks!
