Hi all, I currently have the last plastic Mac Book that was released in mid 2010. It has the following specs: 2.4 GHz Intel Core 2 Duo 4 GB 1067 MHz DDR3 NVidia GeForce 320 M 256 MB 250 GB Sata Disk 99% of the time the laptop is hooked up to a monitor via Mini Display Port. I'm a developer so I have xCode open all the time, and I usually have Safari open with a bunch of tabs (sometimes I need Illustrator or Photoshop open as well). I'm finding that a lot of time I'm running out of memory and get the spinning circle when I believe virtual memory is being used (and sometimes Safari will kind of reset itself). Needless to say it can be pretty frustrating, and I'm unable to upgrade the system to 8 GB of RAM because it's limited to 4. I'm thinking of upgrading to the current 13", 128 gb hd Mac Book Air (with 8 gb of RAM upgrade), and I was just wondering if people think that would be a sufficient enough hardware upgrade to handle the above tasks I mention without getting bogged down as much as I do now? In particular, I'm wondering how the processors compare, the difference in video cards, and if a flash hard drive will make a big difference over a disc one.
