SIRI – Iphone app

Apple is running after an Iphone application called SIRI, a personal digital assistant. Whether you want to know weather forecasts, sports updates, etc you just have to talk to SIRI and information will be provided. It now only provides an interface to type into Iphone, infact one can play around with this application through voice. Thats the beauty of this application thats making it universal. Imagine you are driving along a street, and you need to know the nearest chinese restaurant, you just have to ask SIRI, and you will be given the answer.

Although, the recommendations by the application are not always 100% correct, but it learns with the passage of time with some high level data mining algorithms.

Iphone 4G launch

On June 7, apple’s Iphone 4G is expected to launch. Steve Jobs is due to make the key note address at Apple’s annual worldwide Developers Conference in San Fransico.

Uptill now, apple has sold around 8.75 million smart phones in last quarter. The only carrier being AT&T, analysts predict that by 2011,

apple’s second mobile phone carrier would be Verizon.

No Mac App Store

Just like iPhone app store, apple fans have been anticipating a similar thing for Mac OS X, but to utter surprise, nothing like that is in pipe line.

Apple’s CEO steve jobs replied NOPE to a Mac software developer, Fernando Valente when he inquired about upcoming Mac store. He emailed the Apple CEO questioning him on whether or not such a service would become a reality. After the email was sent, Valente, like many others, was not expecting a response. But much to his surprise only a few hours after sending it, he received one. The email from Steve Jobs was brief and to the point, simply stating that “nope,” no such service is on the way.

It has been a widespread rumor in forums that whether apple would be launching any thing like app store for its Mac OS. Now it has been confirmed that nothing like that is going to happen.
