Which isn't true.... just a very quick example
Shopping for home router (2 days ago for instance)
It makes little sense to buy MIPS today since pricing is more or less the same and performance is much lower (both processing and also usually flash/memory) however it might be a good option in some scenarios (long distance links etc). It's also something the majority of all vendors are moving away from so in terms of longetivity and having the performance in mind ARM platforms are usually a better choice in terms of theoretical longetivity.
Please suggest something else you feel is appropriate
Edit: Less heated....
