As soon as the new Thunderbolt equipped displays and hard drives come out, which will be very soon, the Thunderbolt will allow an MBP or MBA user to have a desktop setup with a full sized monitor, an external hard drive or array, and eventually other peripherals to use a single cable to connect or disconnect the laptop. All that ease of use with mega fast transfer speeds. Seems pretty good to me.
Also, I thought the Sandy Bridge chips were going to "bring massive CPU performance improvements to Apple's most diminutive laptops with little change in power requirements." That also seems pretty good to me.
