I haven't heard the "toy" argument in a long time. I knew that RIM was in trouble when the Iphone 3 came out and I noticed that many of the early adopters were 50 + year old corporate and legal types.
BB apps are getting better, but frankly, they just aren't good enough. More importantly, as good as they are now, they aren't BETTER than iphone or android apps.
If RIM was competitive, I'd be fully supportive (as I have been for 10+ years). But propping up a company for a crappy product because of nationalism... that theory doesn't fly even in the US and its much vaunted automotive industry.
