Just found out that Windows 8 WILL be able to run on ARM based processors...
This, combined with Nvidia's Project Denver(64 bit ARM)... makes for a very interesting future...
Intel should have a true low power x86 chip this month, but they are FAR away from being able to match Nvidia on cost...
So, by this time next year you should have the following types of tablets... (listed descending in order of likely cost)
Windows 8 x86 based tablets
Windows 8 ARM based tablets
Andoird 3.5(or whatever version number) Tegra3 based tablets
I thought 2011 was going to be interesting.. but 2012 is really going to change things up! ARM based desktops, x86 tablets... craziness.
