Tablets

With Apple's introduction of the iPad,Android manufacturers were expected to introduce tablet computers of their own. A tablet computer is loosely defined as having a screen of 4.8 inches or larger and Wi-Fi connectivity. Because many have 3G wireless service, they tend to be more like smartphones with large screens.

Archos was one of the first to market an Android tablet in late 2009. It has a diagonal screen size of 4.8 inches and is called the Archos 5.Archos has since introduced a 7-inch model called the Archos 7.These models come with an actual hard drive for more data storage. Dell has also introduced a 5-inch tablet called the Streak with plans for both a 7-inch and a 10-inch screen size model. Samsung offers the Galaxy Tab with a 7-inch screen. One downside is the inability for many of these tablets to access the Android Market, although that should soon change. A comparison of some tablet computer models is shown in Table 1.2.

It draws the conclusion that habits nurtured in early life concretize into impulses in future for the good or bad of the subject.
