Waste of time blackberry, only a few interest with your update...Lol
The biggest problem on their Z10 is random reboots.
10.1 still doesn't address this issue. Not good.
In my opinion, Blackberry are doing their best in supporting their own in-house operating system; and I personally believe BBOS should be crowned the 3rd ecosystem. I'm not sure why there is more attention towards Windows Phobe; they're not pushing apps as hard as Blackberry are trying.
Apps are a crucial factor in a smartphone these days. They allow the home to perform services/actions which could not initially be done so out of the box; adding after-purchase support for the device.
Microsoft is failing to do this for WP, but BB is trying so hard and their product is much stable and established in a cople of months; over Windows Phone, which has been out for years.
I want BB to be the 3rd ecosystem, and although Nokia and Microsoft did a great job, Microsoft didn't understand the market demands, and are failing at the moment. They can still change this with more features, such as a notification drop down, file manager, persuade more developers etc.
