Hi! As some of you know, I ordered a new Penryn MBP w/ 17" LED so I won't be getting it til March 20th. I just wanted to know if it comes with a built-in memory card reader since I have a Sony Camera (it uses pro duo memory chips I believe). If it doesn't come built in, is there a slot for a memory card reader that I can stick one in (i.e. like in the express card slot) or will I have to attach a USB-type of memory card reader and have an externally attached device that ruins the look of my Macbook Pro? Thanks!
