Apple just unveiled a smart-watch what a technology – the Apple Watch – its first new product line since the first iPad and the death of Steve Jobs the great Apple  technician.


The device runs apps, acts as a health and fitness tracker and communicates with the iPhone.
        While others sell rival products, experts noted that Apple had a history of entering sectors relatively late and then changing their direction.
Apple also unveiled two new handsets that are larger than older models.
The iPhone 6′s screen measures 4.7in (11.9cm) and the iPhone 6 Plus’s 5.5in (14.0cm) – a change that analysts said should help prevent users migrating to Android phones.
They also brought a new service called Apple Pay, which chief executive Tim Cook said he hoped would “replace the wallet” in shops.
The Apple Watch is been controlled by what Apple calls a “digital crown” – a dial on its side that allows content on its screen to be magnified or otherwise changed, and also be pressed inwards to act as a home button.
The display is a touchscreen that can detect the difference between a light tap and heavier pressure from the user’s fingers. In addition, the device runs Siri – Apple’s voice-controlled “personal assistant”.

It offers a variety of different watchfaces, can alert the user to notifications, act as a heart rate monitor and show maps.
Apple said that apps could also be processed on an iPhone, but displayed on the watch in order to extend battery life Although some of these features are available from rival products, one industry observer said the device had the potential to ignite the wearable tech sector.
“Apple has been rumoured to have had a product in this space for a long time,” said Tim Coulling, senior analyst at research firm Canalys.
“I’m sure that for many people, waiting to see what Apple did was a first step before going out and buy a wearable technology product, whether or not it’s an Apple one they get.”
Motorola’s president, Rick Osterloh, told the BBC last week that he welcomed the idea of Apple “growing” the smartwatch market, even though it would compete with his own product, the Moto 360.
Mr Coulling said that other rivals probably felt likewise.
“The buzz that Apple’s entry will generate about wearables is unquestionable,” he explained.
“The watch has a huge marketing budget and uses slick advertisers, so its launch will generate interest around the whole product segment.”
The watch – which comes in three different editions – relies on its user owning an iPhone 5 or more recent model.
It will cost $349 (£216) – which is more than recently announced Android Wear watches from Motorola, Sony and others – and will not be available until “early 2015″.
