The OS can be fantastic but if it isn't supported by third parties it's going to be a bad experience. I loved the Windows Phone UI, but eventually I got sick of the lack of apps and went back to Android.
And no, I'm not talking about the lack of Candy Crush, I mean the lack of productivity apps, online banking, two-factor auth apps, etc. etc.
I've always struggled with lack of concentration, focus, etc and by the time I was on my third Android smartphone I realized that they're Big Glittering Distraction Machines. Personally, I find the lack of apps and games on BB10 a blessing, and the OS is unparalleled for my primary use, email and texting.
The problem's somewhat mitigated by the fact that you can now access the Amazon Android app store and run Android apps, but it feels clunky and slow. Definitely not a good substitute.
Mint, Netflix, any Android app you want can run on BB10 now. That along with everything in BlackBerry World. Plus, you get it on the awesome BB10 OS. Snap is a game changer.
The problem is not what I want, it's about ensuring the survival of the company. There are simply more people leaving BB, despite an excellent alternative OS, than coming in.
I don't really understand how people can want there to be less choice in the market. We have millions of android devices. I am so glad that we still have competition, even if they're losing ground.
