I just pulled the trigger on a new (old model) 17" MBP for $1644. This is the 2009 model. I don't see how come so many companies still have these in stock. I will be replacing a 2009 13". I love the 13" and don't need any more power or better graphics (this is a work machine), rather the only reason I upgraded is to get more screen real estate and 1920x1200. I am a little worried the battery may be wonky after sitting for so long, probably with a dead charge for most of its life on the shelf. Is this a real concern?
