For some people email is all they're looking to do and that's why it feels so much more productive. Unfortunately for BlackBerry it's a pretty small niche.
The problem is that for some reason most companies think they have to be growing tremendously or it's not worth being in business. You can make really good money on a niche - but I guess it's not enough for the current BB executives.

You also have to keep in mind that companies switched from providing devices for employees to providing subsidizes for cell service. That's what my company does. They pay for my cell plan, but I bring my own device. When companies went away from providing people with Blackberries, that also helped doom the company.
Their core issue was that they didn't believe the iPhone was real when it was demoed in January 2007. They thought it was fake. It took them far too long to realize that Apple's vision was the right one. Had they got that immediately like Google, they might still be here today.
Blackberry did make great keyboards and their hardware was nice. BBM was an original messaging leader, but they rested on their laurels.
They've always made very competitive hardware.
But the hardware keyboards were great, as was the consistency of the interface that it allowed, something which Android and iOS need to learn about.
I also think that QNX/BB10 was a great platform. Probably the best mobile OS at the time of its release.
Windows 8 was a really good mobile OS, but it had the same issue.
Even without apps, it would run out of RAM, CPU, etc.
For a company which makes both the device and OS, there's no excuse for that kind of behavior.
All the Blackberry had was a hardware keyboard. Everything else about the platform and OS was vastly weaker. Apple and Google have real, full-fledged OSes (Blackberry eventually got this, but it was really a feature phone with QWERTY keyboard). I do all kinds of productivity and work tasks on my iPhone and the keyboard text input is a small part of that.
Having a real Web browser is mission critical for the work that I do. When the iPhone first came out, that was the No. 1 reason I went with the iPhone over a Blackberry.
The iPhone also has a very robust application ecosystem that is powered by the fact that all iPhones have come with large (by Blackberry standards) responsive touchscreens. I use project management software on my phone. I have note taking programs that sync with desktop. I can even SSH into a server and update html files.
Apple put real computers in users' pockets. Blackberry just made texting and writing emails (not even full-fledged emails either!) easier to write. That's it.
