I wonder if we'll reach the point where some SmartPhone/tablet makers start flirting with officially supporting multiple operating systems on the same device either to end users or carriers. I can think of a couple reasons why the carriers might like this approach. I'm sure enterprise IT departments would prefer to have more control to lock down and customize devices. Even if they don't want to switch platforms at the moment it's not very practical to root and install custom ROMs on everyone's device.
