Re: I know who I believe,
While I agree about BB10 (the only handsets I've seen were on a rather desperate display stand in a shopping centre, plus a few gathering dust in shops), I've seen a fair few new Windows Mobile devices. Probably not to the same level as Android or Apple, I'll grant you, but still sufficient to justify it's place as an also-ran.
I'd sooner take a Windows mobile over either Android or Apple at the moment (And I use an iPhone and have a Galaxy Tab and a Nokia Lumia in the household).
The latter has become somewhat tired, with the cost no longer justifying it's benefits. When was the last time iOS actually gained anything innovative? Even Siri was an acquisition of an existing app. Of course, most of the iFashionistas replacing their iPhones yearly don't care, drinking skinny latte and smugly looking down on the Chavs with old BB or new 'Droid handsets..
The former is a mixed bag of random handsets (some good, some not so much, some waaaay too big...) with an underlying OS by a company who makes money by peddling personal data and advertising - 'do no evil'? Yeah, OK.... Besides, being associated with such an unnecessarily defensive, virulent, obsessive fanboy community sends shudders down my spine.
To be honest, all of them leave me cold at the moment. I'll stick to my iPhone 4 - yes, it's three years old, but it isn't the size of a small continent and runs everything I need and then some without any problems. At the end of the day, it isn't about the badge, it's about whether it does what you want it to do.
