My first smartphone was a BB Pearl.... It was an amazing phone for it's time. The only issue was the freezing and lack of apps. The BB Z10 had considerably better build quality, but the user experience was the same. Constant freezing and lack of apps. According to my phone, it (the Z10) received OS updates almost daily for the 2 months I had it but it's usability never improved. The OS was actually in worse shape when I finally got rid of the phone. It had gone from freezing once a day, to freezing nearly once an hour. I had my Pearl for almost 18 months when I finally got rid of it. On it's worst days, it only frozen 2-3 times a day. Prior to buying the Z10, I picked up a BB Playbook. Of course, as soon as I got it BB announced that it would received BBOS10.....then recanted, then dropped support for the Playbook entirely. That's part of the reason people in the US will never flock to Blackberry. The Playbook had the potential to be big.....but Blackberry made all the wrong decisions and said all the wrong things. It's still a nice tablet, it just doesn't have any apps to make it useful. I've had the Playbook, Galaxy Tab 3 8.0 and a Toshiba Win8 tablet. My son even has a 7" Kindle FireHD. The Playbook has the best build quality, but is the most useless because there's no real apps available for it. The lack of apps is literally the ONLY downside to it.
Enough of that rank. For Blackberry to ever get back to where they used to be, they need to offer something special. Something unique. They also have to offer it before Android and iOS manage to implement it. Right now, they offer nothing that Android and iOS don't aside from no ecosystem and a minuscule app store. Even Android has gestures.....and unlike the Z10 at launch, Android's gestures actually work properly. Blackberry also has to offer their phones at reasonable prices for their features. My Z10 was almost $600 while comparable (more "feature complete") Android phones were in the $250-$350 price range. A proper app store is also a must.
