I don't agree at all, people will still go and buy arm. Which means not only is it not a mistake it's essential.
Where clove tail will come into its own is for cheap business devices.
I'm sure people will still buy ARM as well.... and then get annoyed and confused when they cant get their Windows software working. Having two different OS's for tablets also causes so many marketing problems, especially when one OS (RT) offers no advantage over the other.
It also seems that OEM's agree and are possibly making more Clover Trail tablets compared to ARM tablets. Clover Trail has tablets coming from Acer, ASUS, Dell, Fujitsu, HP, Lenovo, LG, Samsung and ZTE.
