Supporting it in the enterprise environment would be tricky. You don't want users loading their phones with malware and then bringing that infected phone inside the network.

This happens today even with corporate laptops. If they're allowed outside, they will get infected. Working in information security, I send a few form emails each month telling someone to call the helpdesk and get their computer reimaged. If the company has a good enough network team to know how to properly segment a network (and/or implement a reverse proxy) and a security team with enough resources to monitor network traffic, the risk becomes acceptable.

Basically what you describe is BYOD, and it gives me job security :) For the record, I would totally buy the same desktop on three form factors if the same apps and same data could be synced across all of them.
