If you’re one of those that need a few USB ports to power up or connect all sorts of devices but you don’t have enough, I guess you need a hub. Maybe the Dr. Bott T3 USB 2.0 hub can help you with three ports for a mere $20. It has three LEDs that shows which ports are used and a fourth LED to tell you when the hub is powered. The Dr. Bott T3 USB 2.0 hub comes in silver and white and would look great with your MacBook Air.via Zdnet

I’m not sure how you feel about USB connectors because I know it’s a pretty common thing these days but think a little bit what would have happened if we wouldn’t have it. Would we still use serial and parallel cables to transfer a movie or some vacation pictures? I guess not since the speed is not the best.

It all started with USB 1.0 which was very easy to connect but lacked on speed. Then, USB 2.0 (which we use today) came to increase transfer rates to up to 480Mbps and though we may think that’s enough right now, HD movies development and bigger and bigger files will make it a nightmare to use.

This is where USB 3.0 comes into picture to continue the successful story of Universal Serial Bus connectors with speeds up to 10 times faster, hitting 4.8Gbps. It’s supposed to be available in stores in 2009, while we get some specs about it early 2008. Will the story go on? Will USB 3.0 be as successful as those before? What do you think?
