Hi, I have a few questions on my inquiry for the latest Macbook Air along with the Retina 13in. Ever since I used my girlfriends 2011 macbook pro.. Im really hooked with OSX and just feel more productive with it (of course thats just personal thing =P). I have a Sony Vaio TZ Core 2 duo 1.06ghz from 2008 that I have been using on and off, and to me the performance is a bit slow. I know if I slapped in 4gb ram and a SSD will bump the performance up by a lot, but I want a mac now. My dilemma is will the macbook air 1.7ghz i5 with 8gb ram be sufficient? I am a bit skeptical about its 1.7ghz performance. I looked into the retina 13in but Im leaning more to the air cuz of its size and battery life. I use the laptop for school uses mainly excel and powerpoint, but also quickbook for work. And with free time I use Photoshop and Video editing, from my canon DSLR (I dont use it as much once a week about 2 hrs worth of time fiddling unless Im compiling a family video which takes even longer). On top of this I plan to learn Object-C as an extra hobby. So will this be sufficient for my use? Also to mention I have few external HDDs so 128gb SSD will be sufficient for me. So will the air run smoothly without a slow/lag response like the vaio? And will this be enough that I wouldnt need the 13 retina? I know that just 300 more I can get a better screen and better performance, but dont see the need to have the performance if Im not going to be playing games or be using photoshop/Premier intesively am I correct? Along with few articles indicating retina display is slowing down the performances of the MBP. Ive done my research and looked through forums about Core 2 duo vs i5 performances, but I want a bit personal answer, and probably after few responses I will have my decision made up. So what do you guys think? MBA 13in i5 8gb or MBP 13in i5 8gb?
