Are you seriously suggestion ARM has a chance of replacing traditional CPUs? If so you're sorely mistaken. ARM may be heavily embedded into the mobile market (pun intended

) but it'll be a cold day in hell before you sit down at a gaming computer that's running on an ARM CPU.
In fact, by the time Windows 8 roles around, Intel's new Medfield Atom should either be out or close to out and it appears to be leveraged to blow existing ARM chips out of the water with higher CPU performance and lower power consumption.
