The interresting question is: Will it be a common platform
Unlike mobile phones which are usually sold along with the OS, selling a server which can only run one (version of one) operating system is a hard job. People want to choose their own operating system. For this you need sensible ways to make sure one OS image can boot on all machines... at least enough to enumerate the hardware and load proper drivers. (which for security reasons cannot be closed source in many companies)
If such a platform emerges, there will be a chance that it'll be used outside the server business. For example for workstations or "high-end" mobile phones. If we had that, we'd finally be able to run one image on multiple phones and finally have some competition and progress in the mobile area.
