The real issue is the media, every few months we have "new iPad killer" or "new iPhone killer", being announced by the tech Media. Lets have a look at the track record of the media in this regard: The Kin was meant to be the next iPhone killer, and after 7 billion dollars (yes thats a real figure) of Microsoft R & D and marketing, the "iPhone killer" was withdrawn from sales after 90 days, they couldn't even give them away to Microsoft employees. The playbook was meant to be the next iPad killer, its dead and millions of dollars lost, the HP web os was also meant to do the same, didn't even last a month. The zune was meant to be an iPod killer... its dead, and millions in losses again despite Microsoft pushing it for years and years with no real sales that even made a dint in real market share.
I get sick of hearing the next apple killer product is here, and yet when one does some little analysis on the product it self , in this case the surface, its hap hazard design, its confusing two model , not compatible with each other hardware and software, and Microsoft's insistence on only selling in online for the world, and in Microsoft only stores in the USA (just like the zune, strategy, cause that sales strategy worked so well for it last time), one can clearly see that this product is not destined to sell any real numbers, and is more of a prototype or a idea for other OEMS to follow perhaps... but iPad killer... no way in a frozen snow flake in hell is it that.
I am all for competition, for if you don't have it in the IT industry you get things like Windows and all the very boring and non inspiring plastic cheap rubbish laptops and desktop PC's that all the Microsoft OEM's make. There are many things in the current iOS that have been borrowed from Android that help us Apple users have a better experience (though I would argue they borrowed more than their fair share from iOS). The next Windows 8 phones do look good and its OS is a bright light in the "copy cat" smart phone operating systems of late, however that brand new Windows 7 phone you bought on the weekend, hope you like its operating system for the next two years of your contract, as it WILL NOT run Windows 8 phone software, AS NO phone currently released will run windows 8 OS phones, (way to shaft your user base).
Thus all I am saying put things into perspective, take a look at the history and track record of the media and Microsoft in particular, once you do that, it makes it hard to believe that Microsoft has released anything of real note or impact, once again.
