Im just looking into getting a MacBook Pro to replace my windows laptop in order to start iphone development. I will have roughly £700-£900 to spend (perhaps more if needed). Im unsure if it is worth buying an older macbook pro but one which was "top spec" when new, or buy a brand new macbook pro with lower specs. As well as developing id hope to use it for other more labour intensive programs such as photoshop etc. My current laptop has the i3 processor, so it seems daft to get anything less, but perhaps not. Any help would be great, thanks.
