Ultrabook is a laptop substitute for a tablet

We're getting lots of news about keyboard accessories for tablet computers; they're about to invent the laptop. An alternative to this combination is the Ultrabook, a super-light laptop made by several companies.An Ultrabook is a Windows version of the MacBook Air — a sleek $999 computer. Ultrabooks start up almost instantly, have a long battery life (up to eight hours) use an Intel chip and have Intel's Anti-Theft technology. Prices range from $550 to $1,500. Makers include Acer, Asus, Toshiba and Lenovo.Library Offers More Technological Resources Via New Laptops.Toshiba's “Protégé Z830” is the lightest, at 2.4 pounds. The Asus U31 is the cheapest, and we saw it at Amazon for $550.Tell it to remember to get some milk and it stores that to your list. It also listens and captures any other task you need to do. You can collaborate with others in creating a list of tasks or objectives.
The bad news is that Ultrabooks come with WiFi only. But you can buy an adapter to connect it to an Ethernet link when the WiFi signal is weak. Another drawback is that Ultrabooks don't come with a CD or DVD drive. And as long as we're here, they use mini-USB connections instead of the standard size, so you'll need another adapter to plug in some accessories.The bottom line here: The light weight and long battery life are the attraction. Our current Acer laptops are about two pounds heavier than an Ultrabook, but we don't carry them often enough to justify buying the lighter machine.
Cellphone radiation may cause cancer, according to the World Health Organization, but there's still time to panic. One way out is a protective cell phone case. (The other way is not to worry about it.)So far only one protective cover has been certified by the Federal Communications Commission. In their tests, the $50 “Pong” case diverted 65 percent of the radiation that would normally go into your head. Admittedly, the tests involved dummies with gelatin brains, but we've all met people like that and the simulation is considered accurate by the FCC. Signal strength was not affected by the shield and the amount of radiation received was considered safe.
The Pong case is available for the iPhone, iPad, iPad 2 and Blackberry. (If you don't have a 3G cellular connection on your iPad, which costs more than the WiFi-only iPad, you don't need this protection.) The case snaps on easily and come in six colors. According to the journal “Electromagnetic Biology and Medicine,” children's bodies are twice as sensitive as adults to radiation.
