Hi Everyone, I could use some advice - my wife is using a 2010 13" 2.4ghz C2D, which I have upgraded to 8GB of RAM and a 240GB SSD. She plugs into a 24" monitor while at home but is on the road a fair amount as well so portability is a factor. I'm curious, assuming I get her an i5 MBA with similar size SSD and RAM, will there be much of a performance difference with the new processors and chipsets? Her primary tasks are lots of email, lots of tabs in Chrome/Safari with Youtube, Netflix and Hulu running, occasional photo editing, word docs, video viewing. She tends to keep quite a number of programs/tabs/emails open at one time. Attributes such as the lighter weight, long battery life, nice form-factor, will certainly help - but if it's mostly a lateral move than I may save the money and upgrade next year or the year after. Thank you all for your input!
