A laptop computer or simply laptop, also called a notebook computer or sometimes a notebook, is a small personal computer designed for mobility. Usually all of the interface hardware needed to operate the laptop, such as parallel and serial ports, graphics card, sound channel, etc., are built in to a single unit. Most laptops contain batteries to facilitate operation without a readily available electrical outlet. In the interest of saving power, weight and space, they usually share RAM with the video channel, slowing their performance compared to an equivalent desktop machine.
One main drawback of the laptop is that, due to the size and configuration of components, relatively little can be done to upgrade the overall computer from its original design. Some devices can be attached externally through ports (including via USB), however internal upgrades are not recommended or in some cases impossible, making the desktop PC more modular.
A subtype of notebooks, called subnotebooks, are computers with most of the features of a standard laptop computer but smaller. They are larger than hand-held computers, and usually run full versions of desktop/laptop operating systems. Ultra-Mobile PCs (UMPC) are usually considered subnotebooks, or more specifically, subnotebook Tablet PCs (see below). Netbooks are sometimes considered in this category, though they are sometimes separated in a category of their own (see below).
Desktop replacements, meanwhile, are large laptops meant to replace a desktop computer while keeping the mobility of a laptop.

What is the Acai Berry?
The acai berry (pronounced “ah-sigh-ee”) is a small grape-sized berry that grows in the Amazon Rainforest of Brazil. People of the rain forest have cropped this berry as part of their diet for a long time.
The much desired acai fruit is just ten percent of the actual berry. The other 90% is made up of the pit. The acai berry is harvested by the 1000s and put through a process that splits the pulp from the seed to produce a thick, edible puree.
Although the acai berry is well-known in Brazil, only recently has its popularity spread to North America. Doctors, scientists, nutritionists and countless journal outlets rave about its many nutritional qualities and health benefits
This recent shockwave of interest in the acai berry has been aided by Bestselling writer and anti-aging expert Dr. Nicholas Perricone who has touted the fruit as the “Number one super food in the world” in his book “The Perricone Promise” and in appearances on TV shows such as Oprah.
Calling the acai berry “the number one super food in the world” might sound like a stretch, but this view is not unfounded. The little berry is packed with an amazing amount of free-radical fighting antioxidants and is considered to have the best overall nutritional value of any fruit on earth.

Not only is acai berry replacing wheatgrass as the new health trend, it also seems to be the newest fad diet as well. Clever companies are beginning to realize what a big discovery acai berry is and capitalizing on it with well marketed diet supplements. While many of these diet claims are exaggerated, the acai berry has been scientifically proven to contain several important ingredients that aid in boosting the metabolism, suppressing appetite, and building muscle tone.
