I'm seriously considering getting a MBA mainly for its size and portability. I currently own a MacBook Pro 17" unibody 2009 model, its a core 2 duo 2.93Ghz with NVIDIA GeForce 9600M GT graphics processor; 512MB of GDDR3 memory NVIDIA GeForce 9400M graphics processor with 256MB of DDR3 SDRAM shared with main memory3, and 4GB of Ram and 320GB HDD. It's starting to show its age, I use it mostly for graphic design work. Adobe CC, and some audio and iMovie stuff. Would a 2013/2014 MBA that has an 1.4Ghz i5 processor/Intel HD 5000/128GB SSD/4GB ram, be a lot faster than my old MacBook Pro? Or should I do a custom to build with 8GB Ram and 256GB SSD since I heard you can't upgrade the memory on these. Only thing I would have installed on my machine is Adobe CC suite, iWork, Office and my music. So hopefully 128GB will be enough for me. Another concern would be waiting for the new MBA with retina display, and the possibility of a 12" MBA. I like to be able to carry this around the house or take it with me out, hopefully replacing my iPad. I love to surf and chat, email in bed, and I find that the iPad isn't satisfying to use since it has no real keyboard, and I can't really multitask on it, and the 17" MBP is just too big and uncomfortable to use in general. Would like your thoughts and opinion on this.
