CES 2011 saw the debut of what could be the biggest challenge to the Wintel dominance of personal computing since Windows 95 cemented its position. The combination of the Android operating system on ARM processors -- ARMdroid if you will -- grabbed most of the attention in the emerging tablet category on products such as devices such as the Motorola Xoom and LG G-Slate. But it was also clear that manufacturers -- unconstrained by Cupertinian notions of what operating system is best suited to what kind of device -- are willing to take the combination in new directions that come much closer to the notebook form factor. A clear example of this was the ASUS Eee Pad Slider. If having the tablet thunder stolen from Microsoft wasn't enough to make the company uncomfortable, clearly encroaching designs like this were.
An interesting read about how ARM is blurring the line between "mobile" operating system and a "desktop" style operating system, especially with Microsoft making a public statement about how windows 8 will support ARM architecture.
