does anyone really buy blackberry products?

i find it difficult to understand, with all of the various android handsets and the almighty iphone, and even some windows 7 mobile phones, how people still continue to buy blackberry devices, including the playbook. so it isn't surprising when i read this:

the playbook, built on a new os, and with an impressive ui from qnx, seems decent. but having to connect your blackberry to access mail? really? even with a native mail app, i would find it difficult to understand the purchase of a playbook. if you have an android or ios device, you've probably bought or downloaded free apps, which you could conceivably use on your tablet, and some of these apps you may have become dependent on by now.

i understand that many corporations still use blackberry, and therefore employees use/buy blackberries, but it seems like the way that rim has responded to the android/ios tidal wave isn't nearly enough. their products are old, un-innovative, and definitely not competitive in almost any aspect.
