ARM is a brand of processor and has nothing to do with the "full fledgedness" of the software you can run on it.
ARM is not x86, x64, PowerPC, 68k, etc compatible. So you have to run ARM software on an ARM processor, except in emulation.
The PineTab is a "normal computer" unless you only consider computers that run Windows to be "normal". In fact, Windows X will probably run on the PineTab eventually.
You *do* download and install the operating system of your choice on the PineTab. But you're limited to what's available, or what you can make run on it, like any other computer.
