Now Thunderbolt (originally codenamed Light Peak) is an interface for connecting peripheral devices to a computer via an expansion bus. Thunderbolt was developed by Intel and brought to market with technical collaboration from Apple. Thunderbolt essentially combines PCI Express and DisplayPort into a new serial data interface that can be carried over longer and less costly cables. The interface was originally intended to run on an optical physical layer using components and flexible optical fiber cabling. However, conventional copper wiring turned out to be able to furnish the desired 10 Gb/s Thunderbolt bandwidth at lower cost. Later versions of Thunderbolt are still planned to introduce an optical physical layer based on Intel silicon photonics technology.
Seeing that Thunderbolt is based on PCI Express technology, Intel/Apple can use existing USB and FireWire peripherals — even connect to Gigabit Ethernet and Fibre Channel networks — using simple adapters. And because Thunderbolt is based on DisplayPort technology, the video standard for high-resolution displays, any Mini DisplayPort display plugs right into the Thunderbolt port. To connect a DisplayPort, DVI, HDMI, or VGA display, just use an existing adapter.
How does Thunderbolt stack against the rest?You may have realized Apple does not carry USB 3.0 Ports and therefore hopes on the forward movement of Thunderbolt as the new Hi-Speed interface standard.
Thunderbolt-ready devices.

Some early tests done by Apple

So what does Thunderbolt mean for me Today as a "normal' user... Nothing... I have not been a USB fan for hi-speed connects, and Firewire works very well for me when i have to connect my video camera or when connenting external Hard Drives. But i am very happy to know that the day in which i need to connect a second Monitor, back-up my iPhoto library (now at 420GB) or connect to some upcoming cool up and coming gear (all one one port), I already have that port siting there waiting.
As a "PowerUser" I can see no disadvantages in not using this port, even today, as two of my past-times are Photography and Video, working from home means there is a limit to number of devices i can put on my desk. We always need/want faster drives, and a second monitor is always a good thing to have. Being able to have these simple wants over "one cable" is a big plus. This means, Firewire camera to the Raid Drive to a (HDMI) 34' Sony and then to a iMac all on "one cable". Come on... And that is just the start and things to come.
I have always been a Power User, meaning that i always had to buy PowerMacs, but this line of computers have truly have moved me to really consider being a iMac user and not because of price, but because of performance. Starting at i5 4GB of RAM, Sandy Bridge and Thunderbolt @ $7000TT, that is a very easy sell for me.
