Apple Watch makes its debut worldwide

From Beijing to Paris to San Francisco, the Apple Watch made its debut today. Customers were invited to try them on in stores and order them online.

The smartwatch is Apple’s first new product category in five years and comes in 54 configurations — more than any other Apple gadget. So starting today, Apple stores will have staff trained to help you choose.

Analysts are waiting to see how well the watch will sell beyond devoted Apple fans. Apple has a better chance at succeeding than any other smartwatch maker so far, yet it will likely take time before sales reach the kind of numbers that Apple gets for iPhones and iPads.

Samsung hopes to reverse fortunes with Galaxy S6

SEOUL, South Korea — When Samsung dubbed development of its latest smartphones “Project Zero,” it was sounding a note of desperation as sales tumbled and it lost pole position in the crucial Chinese market to rivals Xiaomi and Apple.

The results of its overhaul, the flagship Galaxy S6 smartphone and the S6 Edge, go on sale in 20 countries on Friday. Samsung is hoping a revamped design, a more intuitive interface and less clutter will help claw back lost market share.
