IMHO, a device can be made for handheld use without also being pocketable. You're not going to be using the Netwalker on your lap very easily.

I would argue that it is pocketable, but I understand that not everyone has cargo pants or jacket pockets to carry their devices around with them.

Anyway, is always nice to see another device of small proportions, especially if it brings a new, useful form factor to the table, so good luck to ya.
