hello all,
I just wanted to report that my N900 had the very well known problem with the USB port. I took it to the nokia center where I bought it here in Thessaloniki (Greece) and they replaced it in a little more than 3 weeks with a brand new board (new IMEI too of course). The touch screen, the plastic cover etc is still the same.
Now I only have to hope it won't get loose ever again.
