I will be buying an N900 in a couple of weeks. It happens that I do not live in the USA but will be travelling there soon, so, I will have it shipped to my hotel. It turns out that there are known "problems" (improvement opportunities, others call it) with the N900; as I have read in the forum: the fragile USB issue, dead pixels, ... What would be your checklist of things to, well, check or test, on a new N900 and make sure everything is all OK or, take the drastic decision of shipping it back ? This should be an interesting exercise and, hopefully will help new buyers of N900, specially "remote" buyers as me. Thanks in advance.
