I'm not familiar with RIM but your AAPL comment is just wrong. If you look at the data you linked you can see that the results of 2011 Q1 are almost as high as Q4 2010 (typically the best quarter of the year). It's lower than the previous quarter but that's just because of the holiday season.

2011 Q1 was the second highest quarter in revenue for Apple in its _history_ so they're definitely not going down.
