I am office-bound all the time. But this week I needed to get involved to move the contents of one warehouse into another. I spent three days lifting and moving heavy materials. I had my Blackberry clipped to my belt. First it fell off my belt onto the concrete and into a muddy puddle. Then it fell off a loading dock onto cobblestone. Then there was another fall onto concrete.
Then I figured out I had best store it in my pocket.
I mention all this because I am amazed how I abused the thing. It has a few scratches but it works fine.
I can't imagine my old Palm Tungsten (no phone) would have endured that abuse.
Blackerries have severe limitations. But they sure are hardy.
