At my job they've been hoping Dell comes through with a tablet. They began by giving Axim X30's to all our builders and when Dell stopped making them our company IT is dropping the IT support. Difficulty there was the corporation had sunk a good deal of money making a portable and dock-updating version of the construction scheduling software by that time.
A long-nebulous plan that the Dell tablet would make marking the house building plans entirely digital has been floating around. I'm not entirely sure our builders are geeks enough to do this but the Dell tablet would have to be robust enough to make this possible. Also has to survive the environment of a pickup truck at construction sites too. The Axim did okay once they bought the Rhino Skins.
The up side is they're offing the Axim's with a $50 purchase fee to employees. Down side is we can no longer sync them to our work computers.
