Interesting points, but they illustrate how personal the perception is when it comes to how complete a phone is. Custom profiles and ringtones are all Im missing at the moment. Like everyone else, I rushed to the Ovi store and downloaded lots as well as maemo downloads, but most of it I haven't kept as the browser is enough for me - that in my opinion is the one killer app for the n900 because it is just so good. My guess is that the n900 will never have 1000's of apps as they just aren't needed, yes there will be some great ones, but with conversations and the browser, there doesn't need to be that many as the phone already has alot of functionality buit in.
Now Im kicking myself for staying with Windows Mobile for so long - the n900 is a breath of fresh air..
