I have none of the issues the OP listed, with either of the (2) 900s I have/had, especially on a regular basis. I have had general freezing every now and then (Firefox), but not to the point where I'd blame Nokia for putting out a shotty product. To say that its lagginess is a "Nokia specific oversight for the product as a whole, and a chronic issue" is going a little bit far. I've had "some" experiences of slowness in all (3) of my last smartphones, at one time or another, but its been more of an exception, rather than the norm.
