The new Apple lineup, including the 13″ and 15″ MacBook Pro, might be showstoppers, but the simplest yet impressive innovation I’ve seen comes the new Apple 24″ LCD screen.
Apparently Apple’s 24″ LCD has a symbiotic relationship with the MBP. It’s turns the MBP into a “desktop” setup just by joining three cables from the LCD, namely the Mini DisplayPort, USB, and MagSafe power cable.
While there’s no real interlocking between hardware, this “dockable” feature is nevertheless a real timesaver for dual screen users like me. I actually bought an additional power adapter that’s a permanent desk fixture, just so that I don’t have to dig and crawl around with one everytime I switch from mobile to desktop mode.
You can read about this feature at the bottom of the MacBook Pro “Graphics” page.
