Hi, After closely following Apple news for a year, I've finally decided to buy a uMBP 17' when the back to school promo comes out. I know this has been asked before, but that was for the Macbook, not the Macbook Pro, which has an ExpressCard slot that can offer a whole range of uses. I currently have a VX Revolution mouse and is looking forward to buy a 500GB My Passport Studio for general backup and Time Machine, and Apple In-ear Headphones for listening to music. For the ExpressCard slot, I am still deciding whether Firewire, USB, Card Readers.... would be more useful. Any input would be appreciated!
