I find the "its not a REAL computer" argument quite amusing.

It seems like some people are trying to say "If it doesn't run on x86 instructions, its not a computer" which is plain silly. Were the old Macs not a computer then?

Just because you cannot run Windows on it doesn't make it inferior. The point is, Linux can run on a wider variety of architectures (old and new) because its so modular. You start with the kernel then add only the bits you need. How anyone can see that as inferior to Windows which needs stupid CPU power and RAM requirements these days, is beyond me.
