In 1973, Bob Metcalfe sent an internal memo to his colleagues at Xerox proposing a local system of interacting workstations, files, and printers. The devices would all be linked by one coaxial cable, he said, and would run within a local area network. He called the system an Ether Network, or Ethernet. And 36 years later Ethernet is going on strong, although the technology has changed more than a bit on the way. In this original vision, there was no need for hubs. Somehow once everything became balanced twisted pairs the “ether” became segmented into little mini-ethers held back from each other by digital logic.
Photo and original diagram of the world’s first ethernet cable web page has a nice picure of the first Ethernet cable installation and first drawings of Ethernet vision.

Have two Samsung LCD 650 series TV’s. One has Yahoo Widgets that allows Amazon Instant Video with Prime to be streamed. The other has Samsung Widgets with a Yahoo app that can not be loaded/run. When it works, it’s great! However, it is not always enabled by the manufacturer (Samsung) even though they advertise that it is installed/available. Sure would be nice if Amazon/Yahoo could exert some pressure on the manufacturers to provide their services, especially when they advertise it. My Tivo HD and Tivo Premier both allow Amazon video on demand but do not support the Prime Subscription services for steaming either.

The Android 4.0 Mini PC is the lightest mass-produced computer we’ve ever seen. Though it’s not as powerful as most phones or tablets, this device delivers strong enough performance to use as a secondary computer or set-top box.
tomi says:
To which specific Android 4.0 Mini PC you are referring to?
Can you post more details?
