Hi. I have a Mac Book Pro 15 inch with 8GB of RAM. From 2009. It's not "i5" or "i7". It is still the 2.8Ghz Core2Duo. On Photoshop CS5 or running Apache/PostgreSQL, it's showing its age now. I was really excited that this new MBA launch has 256GB of SSD, but I'm disappointed that the memory is still at 4GB. Looking for impressions from people who've got the i7 + 256GB + 4GB version of the MBA and use designer tools or programming/DB software. Is the performance worth it? I know that when Photoshop runs out of the 4GB memory it will begin swapping to what's now a very fast SSD drive, but I wonder if that is truly as fast as 8GB of memory. Thanks for sharing any experiences!
