Just need to know some things first... I am thinking about going for the 13" 128GB MBA. Standard is 4GB memory, right? So, if I buy it with 4GB and want to upgrade to 8GB at a later date, can I do that? Or would I have to opt for the 8GB at purchase? What does the Apple Store mean by "Turbo Boost up to 2.8GHz"? How great is the MBA performance-wise in terms of Photoshop and basic gaming? I've been reading about some displays on the MBA not looking so great. Is this a real big issue for any of you guys? And how does it fare in daylight (sunny) conditions? I typically always buy Apple products at the Apple Store; however, I've been going back and forth between buying it at Best Buy as well. I know I can get the college discount at the Apple Store, but would I be saving more money buying it at Best Buy? Does the Apple Store price match? Thanks for any help!
