I’ve seen this news on several sites recently and and it seems quite ridicules to me:
1) Google use Windows. Why did they start using windows? Was this so highlighted as their decision to stop using it?
2) Google offices in China were hacked because they used Windows with Internet Explorer. So, Google, why didn’t they use Chrome? And what version of IE that was? IE6? LOL, better late than never :-)
It seems that Google starts marketing campaign to promote their own OS (Android version for tablets?). Hardware manufacturers have said that their ‘iPad killer’ is not ready because of software (that is, Android). So, does it seems we will have some news in tablet world soon?
Also, there are rumors that Apple is going to use Bing instead of Google in iPhone 4g, so this Google's move (they stop using windows and start to use macs) can be somehow connected..
