The first majorly successful tablet computer, the Apple iPad took the world by storm in early 2010. Although it was originally met with some skepticism and many jokes, it has sold millions of units in the short time since its release, and is probably the most popular tablet computer ever.
The tablet is a 1.5 pound, flat touch-screen device. It works on the same operating system as the previous iPhone and iPod, and runs software made for these devices as well as programs specifically made for it. Unlike most other touch-screen tablets, the iPad is intended to be controlled with a bare finger, and requires specialized styli or gloves if users prefer not to use their bare hands.
Apple co-founder and CEO Steve Jobs admitted that the idea for the iPad actually came before that for the iPhone, but that he quickly realized a multi-function smartphone could be made using the concept. Development of the former was put on hold in order to pursue the latter, and when the iPhone was established, research and development commenced to allow announcement and release of the iPad in the early months of 2010.
The small Apple tablet has a 9.7 inch screen, which makes the device somewhat intermediate between an iPhone and a Macbook laptop computer. There are two versions on sale-- one has only wi-fi connectivity and the other connects to the internet with 3G cell phone networks when a wireless network is not available. The latter choice is more expensive.
The 3G version comes unlocked with a micro-SIM card slot in the US and most other countries, and can be used on any GSM carrier's network. The only country whose iPads are sold locked to a carrier is Japan. Also available for separate prices are three different options for storage capacity-- 16, 32, and 64 GB flash drives. The storage capacity is incapable of being upgraded, unfortunately.
The battery that comes standard on an iPad is an internal lithium polymer battery, which should last around 10 hours after being completely charged. They are intended to and capable of charging at a high current (2 amperes), which is around four times as fast as the connection between an ordinary USB port and the tablet's battery allows. To charge at full speed, there is a wall adapter, and some new Apple computers have the capacity to charge at this speed.
Accessories for the iPad generally have to be purchased from Apple. These accessories include a keyboard kit, which allows the user to plug their device into a stand-alone keyboard, a case that also functions as a stand, and a dock and several connector kits. A power cord for charging at full speed from the wall is also available as an accessory.
