I've owned unibody MBPs in 13, 15 and 17" sizes and presently couldn't be happier as a proud owner of the new 15" rMBP, it's an awesome laptop. However, I recently acquired an old 2009 C2D 13" as a colleague was getting rid of it. It is a bit bruised and battered and obviously chugs along next to the retina, but I thought I could give it to the kids to do homework on. But, after using it for a day or two, it got me thinking that there is something so perfect with the design of this machine as an everyday notebook, despite recent trends towards thin and light, and all flash. I hear the concerns around the screen res looking dated but, as a web browser and e-mailer notebook, I personally still love this form factor and will be sorry to see it dropped if the impending retina 13" spells the end of it. Chuck in 8GB of RAM and an SSD and it's still good to go for a few years. Does anyone else understand where I'm coming from about the design?
