After making Gmail available to all without invitations, now Google is adding more features to it. One big feature is you can read other emails in your Gmail inbox! which was introduced few months back. Competition between email giants Gmail & Yahoo made them to give huge services without any cost. If you look back 3-4 years back it was hard to get an account with these feature set even if you are ready to pay for it. Few days back I posted on Yahoo?s move to make mail storage unlimited. Now its Google turn & it increased attachment limit from 10MB to 20MB. But this is not enough from Google to compete with Yahoo?s unlimited storage. Google needs to think about providing unlimited storage to its users also. According to my friend Marc, the secret behind ?Unlimited Storage? is most of users will not use much MBs of their account. In the meantime there are few rumors about Microsoft to acquire Yahoo to compete with Google. Another rumor says Microsoft & Yahoo will merge & work together to compete with Google. Microsoft is also eying on Google?s online advertising market, which is huge income source for Google. Now a day almost every site you visit will be having ?Ads by Google? (Including mine!). Let sit and watch fight between these giants & finally end user will be benefited.
