Um yes I have actually - and I didn't mention anything about you having to take a step backwards - I was simply pointing out in the post you quoted that there are a limited number of things that can be fixed in software.

That being said - comparing one Nokia to another without knowing the exact hardware in each is as stupid as comparing the N900 to a dedicated camera. Just because one Nokia had a certain set of HW doesn't automatically mean the next one will have the same or better.
