I'm pretty sure that should read "had much less market penetration", because Android and iOS both currently have larger market share than RIM (according to Nielsen: http://www.marketingcharts.com/wp/wp-content/uploads/2011/03...). I'm honestly surprised RIM had any sales growth, at all. I simply don't know anyone still using a Blackberry, even among people who were formerly absolute fanatics.
I guess the enterprise market moves slowly enough to keep them afloat for another couple quarters, but it certainly doesn't look good.
