I work as a web developer. My current work horse is a late 2008 13" unibody macbook with 2ghz, 4gb ram 140GB hd which has served me well for the last almost 4 years, however in the last few months has started showing problems (since upgrading to Lion). It takes 3-4 restarts every morning to pick up the wifi hardware, when I wake it up from sleep it loses the wifi hardware, the screen sometimes gets lines through it, making it unusable, which can only be fixed by wiggling and twisting the lid back and forth and will occasionally just freeze on me randomly, forcing me to power off and restart (3-4 times so it can pick up the wifi adapter). With the updated machines (rumoured to be) only a few days away I've decided to upgrade. Obviously we don't know for definite what is coming on Monday so based on current specs... would an air (I'm looking at the current 13" 256GB machine) be a good buy for me? Aside from the issues mentioned above, my current machine runs fine. Only causing me slowdown issues when I have photoshop running a larger file or firefox has a large number of tabs open. It will also struggle with xcode and Final Cut Pro X. I will routinely have Coda, MAMP pro, Photoshop, Mail, Chrome, Firefox, Quicksilver, Terminal, Console, Sequel Pro, Cyberduck and Spotify open at the same time. I like the idea of an air vs a pro as I travel quite a lot and I find them aesthetically pleasing but would like something that will see me well for the next 3 years. Would an Air be able to cope with my needs? Obviously it will be much more capable than my current machine. I hear the solid state drives make a huge difference with photoshop?
