Well, finally I found somebody that gave me the reason publicly. And guess who: Rob Bushway from GottaBeMobile.com
Along with Hugo, Dennis seems enthralled with the idea of wearing the OQO on his belt, and he couldn't wait to begin trying out the new belt case. Well, I have my own thoughts on that issue, along with it being called a pocketable device, so I thought I'd pass them along.
Here is his video about this topic.
I agree with you 100% Rob. I never have carry my Pocket PC in my pants pocket because it's too heavy and bulky so imagine a almost 2 pounds device!
Sorry mate, but the OQO 02 could be the best machine in the world but still... it's not pocketable.
