I'm looking at getting a new Macbook Pro 15" for University (Comp Sci.), web design and development. Might do some gaming if I ever get some free time. I'm not really sure whether to buy now, or wait for the update coming in the next month or two. Do people think the changes will be significant to the MBP models as the buying guide says they're up for updates in the next ~30ish days. My only worry as a student is if the prices go up from £1500 for the mid-range 15" model, as I'm really stretching my budget to afford a MBP. Do I need the mid-range model or could I afford to drop down a model? I'm trying to get at least 2-3 years out of the laptop before upgrading.
