When you move from the most advanced platform available to a system that doesn't compare at all (WP7) and then say "it's not really missing much features" (when in fact it misses all of them).... What does this tell us?

It tells us you never depended upon, used or even noticed the features Maemo on the N900 offers and the WP7 phone lacks. It tells us you don't actually need a smartphone. It doesn't say that feature-wise WP7 can compete with Maemo or Symbian.
