I'm thinking of getting a 15" or 17" MBP for home use and occasional portability. My needs are fairly basic and it's only for the larger screen size that I'm considering the Pro machine. On ebay the ones in my price range seem to be 2007 and 2008 models. I will be running Office (preferably 2011) and using the web, for the most part. I like to have many apps/browser windows open, but I don't do anything very processor demanding (no video editing or anything). I never considered a pro machine before so I don't know anything about their history. How are these machines? Will the work for my needs? Is one year preferably to the other? Worth it to shop hard for a deal on a 2009? What would be a good deal for them and what would be a steal? Any thoughts welcome. Thank you!
