Yes. As far as productivity is concerned Android or iPhone did not match my blackberry. I remember typing out entire class assignments on my phone during train journeys and sending hundreds of BBM messages every day. I barely do it with iPhone. There are simply too many distractions.

I think Blackberry is a bit like Yahoo! where they focused too much on sales and marketing and did not invest well in engineering and product design. When even Gingerbread Android could detect dates in emails and let me create Calendar events based on that Blackberry could not do such a simple thing.
