TBH they need a change. While the playbook didn't do well its the only tablet I've considered due to bridge. If android had a bridge feature option I'd be sold on the transformer or, if it ever comes, the memo. Yet due to their phones being poor that's why I've not got or will ever get it. For me it really comes down to lack of features on phones, no HDMI out, no front facing cam, no dual core, poor market compared to comp (they even miss some swapables I'm looking for). The hardware keyboard, BBM (few friends overseas with BB's) and lower data useage (from what I've noticed) isn't enough to save it.
BB useage here is still on the up, its very popular among kids (mainly curve devices) and quite a few people have moved from iphones to it. Here nokia (smart phone only), windows devices are non exsistant. I haven't seen a single user in well over 2 years. Android is increasing in popularity but no where near the level of BB or iphone. I'm always surprised to hear how unpopular BB is.
