Tablets Google Vs Apple
Google has unveiled an operating system for tablet computers aimed at ramping up the competition with Apple's iPad.
More than 15 million iPads have been sold since Apple launched the gadget in 2010. The latest version of Google's Android OS is called Honeycomb and it has been specifically optimised for tablets.
The features include the ability to buy applications from a computer, buy features inside the app, video chat and improved graphics.
"This is a serious investment of years of design and engineering to really nail the experience for a larger screen," Hugo Barra, Google's director of products for mobile, told BBC News.
"This is not a large phone - we wanted tablets running Honeycomb to not just be bigger but also to be better."
Motorola will be the first to bring a product running Honeycomb to market. Its Xoom device is due to go on sale this month, although a release date and price have not yet been revealed.
"Honeycomb brings Google closer to parity with Apple and underlines the battle between these two titans," said Ben Parr, co-editor of technology news site Mashable.
"Google has its strengths especially in the cloud, with their open source platform and integration with other Google products like Gmail and Google docs," he said. "But Apple has the design edge and a vast number of apps as well as a new iPad expected in the next couple of months."
'Big win'
This now means that users can browse and buy apps directly from the web. Previously users had to purchase through the Android market directly from the device making it difficult to find, download and buy apps.
Thanks to the cloud, users can send apps directly to any Android device with just a few clicks of their mouse.
"There's no wires, no synching with computers - none of that nonsense. Everything is connected," said Chris Yerga, Android engineering director.
Technology blog TechCrunch called the webstore a "big win" for developers.
"It lowers the hurdle you have to go through to buy an app," said Jason Kincaid of TechCrunch.
"If you are bored online, I can imagine a lot of people heading to the webstore and clicking on five apps before they have really thought about it."
Google calls Microsoft a copycat (week in review) Read more: http://news.cnet.com/8301-1001_3-20030639-92.html#ixzz1DCt8ySpD
Google has a harsh word to describe Microsoft: plagiarist.
After noticing curious search results at Bing, then running a sting operation to investigate further, Google has concluded that Microsoft was copying Google search results into its own search engine. The story began with Google's team for correcting typographical errors in search terms, which monitors its own and rivals' performance closely.
Next came the sting, which featured a one-time code that manually ranked a page for a specific term. Google then had employees type in those terms from home using Internet Explorer with both Suggested Sites and the Bing Toolbar enabled, clicking the top results as they went. Two weeks later, Bing showed the Google results that had been hand-coded.
A Bing executive acknowledged monitoring what links users clicked but essentially described it as letting humans help gather data through crowdsourcing.
However, another executive was adamant that Microsoft was not using Google's search results.
"We do not copy results from any of our competitor. Period. Full stop," Yusuf Mehdi, Microsoft's senior VP of its Online Services Division, wrote in a post on Bing's community blog. "We have some of the best minds in the world at work on search quality and relevance, and for a competitor to accuse any one of these people of such activity is just insulting."
