Hi guys, This is my first post and I've read of a few of the threads regarding the new Air. My situation is my mid 2009 MacBook Pro has been a trouper but is now running quite slow, firing up, opening iTunes, iPhoto and the like. Still does everything but after 5 years I'm keen to upgrade. I waited for WCDD or whatever it's called and no hardware announcement. The fact that I don't NEED a new Air now but would like one, how much of an improvement do you think the Retina will likely be? Besides from the display. Coming from an '09 Pro I'm of the understanding that the current Air is a better display. Also is it wise to purchase an Air now with Yosemite around the corner? Is the current Air likely to not handle the new software as well as one would say if it was released in August? The specs on the current I've been looking at are 11" i5/8gb/512. Any advice or thoughts would be much appreciated. Cheers.
