First i would like to say I'm a graphic designer and do music and video recording. I had purchased a pre unibody 2008 the week the unibody was announced. I'm not rich so i went with the based 2.4 model. Begin of this month I decided to sell it and get a unibody. At first i was going to get a new 2010. But i found a good deal for a late based 2008 that was purchase in june 09 and had 3 years of apple care and 4gb and a 500 7200 hd. I was alway wondering if i made the right decision because of the new processors. I was aware in 2009 they made the screens gaumet %60 better and an sd. What i liked about the 2008 was the removable bottom and the express card slot. so my friend brought over the new 2010 and we did a comparison, and all i can say is im glad i made the right decision...i just love the look of it over the sd update. The 2010 screen is nicer, it didn't have hi res. As for speed it was faster but not as much to where i would spend +900 extra. I've been throwing intense photoshop edition, music and video editing and have yet to have a prob. so for those that have a 2008 unibody that was thinking about selling and upgrading to 2010. Unless its necessary or you have the money stick with 2008.
