Windows on ARM ? Will not run third party x86 software ! Being Windows it will be painfully slow on ARM. On MIPS and ALPHA there was the advantage of the faster higher performance processors. Maybe it is the Windows Phone software, which runs ARM, and has been modified to run on a Tablet. Do not see much traction there either.
Let us see if the x86 tablets to be announced at CES gain significant consumer acceptance.
I used to work on Windows on Alpha. Got all of those shiny MSDN CDs several times a year.
Also, don't forget Itanium.
I think that the investor concern is that low-end mobile devices will choose ARM over Atom.
There is so much software out there written for x86 - does Microsoft expect software producers to recompile and port all of their code? What about assembler code? Apple's solution of a translator worked but that's because they were going from a slower platform to a faster platform.
Obviously, in that era, Internet is not a commody for the mass. I don't think what's happening now is not same like in the past. Processors based on ARM architecture has became commodity unlike MIPS and DEC Alpha in 1990's.
It's not a showstopper, just something the ANALysts will point to in January to show why Intel won't go anywhere. The same with Intel's announcement of tablet designs. Of course, those will only take away from Intel's larger notebook revenues...
