Hello, I am starting a master's program this fall and will be using software such as the Adobe Creative Suite (Photoshop, Dreamweaver, Flash), Captivate, etc. The school recommends having a computer with at least 4gb of RAM; my beloved 4 year old white Macbook can't be upgraded to more than 3gb (2 GHz Core 2 Duo with 1GB 667 MHz DDR2), so I think it may be time to upgrade. I know there is a new Macbook Air coming out, but I don't know if that will have 4gb of RAM (upgradeable to 8gb would be ideal, just in case I need more) and be sufficient to run these programs smoothly. Should I go with a new MacBook Air, if it has the RAM, or a new MacBook Pro? Or something else? Any suggestions from others who run this type of software? Thank you!
