For example while reading the article I thought that Google had actually announced a tablet called play. Then towards the end I started getting suspicious, and did a Google search and seems like there is no such announcement. Play is just a name of a marketplace as far as i can tell.
I still am not sure whether there is an announcement or a rumor of a tablet called Play.
If you want to be taken seriously you should qualify the more drastic assertions you are making. You can use terms like "I believe", or "so and so announced" or "as my analysis below shows", etc. Even the more wimpy "sources say" or "rumor has it" is better than reporting rumors as facts.
Of course it does not seem that the writer is even reporting rumors as facts here. He is reporting wild-ass speculations or even fantasies as facts.
