I find it odd with the USB port issue. I have had my N900 since release. I plug it into the charger every night and use it on PC alott at work etc. Never had a USB port issue. But I will admit once people announced it I have always carefully aligned the cable prior to inserting it.

In regard to a replacement I used to work as a tech in a retailer and we used to have great difficulty with Nokia under warranty. They were only good for dead on arrival. So I don't know how well that will work. However I'm in Australia so it could be based on region.

Oh and on another note I made the mistake of getting the N97 on launch the GPS worked for about 2 months I had such a battle to repair it I gave up. Bought a replacement case fitted it myself and used copper for the antenna. N97 was awful I only fixed it cause my girlfriend seems to like it haha. But yeah Nokia in my experience don't believe their products can have flaws.
