I think that something will change in the desktop market, but I'm not sure if it will be ARM or not if it will be something almost as drastic as getting rid of some of that legacy compatibility that bloats modern CPUs.
In any case, as Yuri said, it will all depend on software. It doesn't matter how efficient your SoC is, if the software doesn't support it or doesn't run as well, people and business will buy the other option.
And Marth, you give one step forward and another back. I hope you manage to fix all the loose kinks soon and can finally enjoy your new PC.
Please excuse my bad English.
