I hope everyone thinking about buying an MBA reads this thread. So whoever ressed an old thread did people a service.
I have a 13" MBP, the first thing I did with it was replace the HD with a Sata 3 SSD that blows the piece of crap in the air out of the water. Then I still had room for a 1TB hard drive in the optical bay slot.
BTW, your ram is soldered to the logic board in the air. My MBP has 16 gig which cost me under $100.
With my SSD, the MPB is so much more powerful than the MBA it's just laughable yet there's still nuts here who say the air is faster. The people who think they should scrap the 13" pro (apple's best selling mac by the way) in favor if the air are idiots.
So, my shiny pro is far more powerful than your air, has an SSD as well as a 1TB HD, and with no external drive tied to it, mine is more portable too.
So tell me again, why anyone would even consider an air?
