Low-end PCs in China, India, etc. Intel is selling even its Atom-based Celeron and Pentium chips for laptops at quite the premium (about $110 and $160 MSRP, respectively).
I wouldn't expect these very first devices target that market, though, possibly because Qualcomm wants to be associated with more premium devices, but I think we'll see these chips in lower-end cost-competitive devices, too.
Windows RT was not a failure because of ARM, or because the hardware was not capable. Windows RT was a failure because, once again, Microsoft showed that they are completely incapable of reading the market. They tried to market a Windows experience to consumers and then did not deliver on the Windows experience.
You might be replying to the wrong comment. I didn't say anything about Windows RT being a failure. The only meaning I was trying to convey was that Microsoft DID try to push an ARM platform many years ago.
Ah yes, the version of Windows with zero software.
Nothing about Windows RT was done in a way that indicated that they were serious about pushing it. How could you possibly sell people on a version of Windows that does virtually nothing that people would want to buy Windows instead of Android or iOS for?
