TouchPad

A touchpad (or trackpad) is a pointing device featuring a tactile sensor, a specialized surface that can translate the motion and position of a user's fingers to a relative position on screen. They are a common feature of laptop computers and also used as a substitute for a computer mouse where desk space is scarce. Touchpads vary in size but are rarely made larger than 40 square centimetres (6.2 sq in).[citation needed] They can also be found on personal digital assistants (PDAs) and some portable media players, such as the iPod using the click wheel. Stand-alone Trackpads are also manufactured for wireless function.
HP TouchPad crushed by Apple iPad:
HP’s radical decision to close its smartphone and tablet unit means the TouchPad, the firm’s competitor to the iPad, lasted just 48 days on the American market before being made effectively obsolete.The device only just outlasted Microsoft disastrous Kin line of mobile phones, which were available for 49 days last year before they were euthanised.In Britain, where the Touchpad reached shops on July 15, its challenge to the iPad was even briefer. Its tenure in Australia, where it was released on Monday, must rank as the one of shortest in history for a consumer electronics product.Harvey Norman, the TouchPad’s exclusive retailer in Australia, has already announced that buyers will get refunds. But for British owners, who paid up to £399 for the device, there is no sign they will get their money back.In its short life all the omens for the TouchPad have been grim. After a month on sale, HP slashed the price on its website by $50, although it said this was a limited time offer. At the same time bricks and mortar retailers were offering up to $200 of the $599 list price, however.HP said the discounts were designed to entice students ahead of the new school and college year, but such claims appeared callow when it emerged earlier this week that Best Buy, America’s biggest electronics retailer, had sold only 25,000 units out of its TouchPad stockpile of 270,000.
