We've had this debate before. I know you're a fandroid although you won't admit to it. I know you won't give in until you get the last word. I won't play this game for long with you. The tablet market is taking off NOW. Apple has the lead. But the market has not solidified. My bet is on the vertical integrated solutions, like the Playbook, the iPad and the Touchpad, not on the fragmented solutions from a myriad of Android vendors that compete against each other and do not offer the user a solid and integrated ecosystem. Sure, all these OEMs run Android, but each is competing and undercutting the next guy. For example, nothing in the Atrix ecosystem is compatible with Samsung's line. Then you get the oddballs like Kyocera and their double screen offering. I'm not worried about HP because they have something few other vendors have - distribution and the scale to fight for the parts needed for their products and the ability to take a loss the first year. Motorola has already had to price its Xoom tablet out of reach of the average potential Xoom buyer because it can't afford to leverage supply discounts like Apple, HP or Samsung.
Motorola cannot get its Xoom in Walmart, Price Club, Target et all. It relies on Verizon alone. HP can command retail space on all the major electronics chain and sell units directly to enterprises as parts of bundles that LG will never be able to match. Only Microsoft, IBM, and Oracle have that kind of traction.
Games are not irrelevant. If they were, Sony-Ericson would not be basing their own Android ecosystem on the Playstation-based Experia. Microsoft would not be touting X-Box integration with WP7. iOS took off first because of games.
The mission critical apps you're describing are already there, including the integrated Cisco security architecture and full exchange server compatibility that Android and iOS are still dreaming they had.
And just so you know a navigation app is currently in beta for webOS 2.0
