I am an avid PC user, and I work for SDSU as a PC repair guy. I am a graphic design major and my second year is rapidly approaching. I plan to buy a MBP later this year, but I am torn between the 15" and the 17". I have read many articles on performance to price ratio betwixt the two models, but I am unable to reach a conclusion. This laptop will be used with adobe cs4 extensively, and as my daily machine. 15- Has size and price on its side, and a decent deal of performance. This machine is within my budget, and would last my entire college years remaining. (three) 17- Has neither price or size, but screen real estate and performance. However this is at the top of my budget. I like the 17" model for screen real estate and preformance, I havent read to many articles on real world portability, and spec wise it doesnt seem too much larger than the 15" I like the 15" model because it fits my budget better, but I am worried the screen and performance may not be optimum. Side-notes I have little preference for glossy/matte screen, and this laptop must last through college and hopefully then some. Any input is greatly appreciated.
