There are several possibilities. 1. ARM tablet. 2. Intel tablet. 3. neither. Both rumors are false. 4. both tablet types. Both rumors are true.
Companies are organized into divisions. A natural way of dividing a company is to have a MOBILE division and a COMPUTER division with substantial inter-divisional rivalry. It would not be crazy for Samsung to have one of each. They could have an Intel based tablet from their PC division and an ARM based tablet from their ARM division. Samsung certainly has the resources to build two tablets.
I am not sure what you mean by "Samsung will take Intel down" but Samsung will have to develop a product they can sell first. It will take more than a tablet copycat to damage Intel.
I am going with number 4. But the thing of interest will be, what will people take? You can only have one device.
My question is about writing apps for Windows 8. There will be the x86 version and the ARM version. Will both apps require different code? Will either use Windows Phone code?
As long as Microsoft doesn't have another Vista on it's hands it will grow to be one of the largest install bases in the world in a few years if PC's keep their 400 million annual sales pace. Of course, it would require that apps actually are popular on this platform.
In the past Microsoft has tried to make keep the wraps on Office by not making things like One Note available on anything but Windows and Windows Phone/Mobile. I wonder if they are going to try to promote the closed system approach in the future for apps? I guess all will be know next week!
If you write the APP in C# (Microsoft created when Sun won the Java lawsuit) or Java or language that generates bytecode, they are translated into a portable BYTECODE that is "interpreted" and can be the same BYTECODE on either (ARM or x86) environment.
The downside of interpreting bytecode is the substantial negative performance impact when compared to running native code. Portability is traded for slower operation.
The problem with Office is that it takes a couple GB of memory and a coupe GB of disk space. Office is not exactly "tablet friendly".
