It's just yours. However I think there might have been a bad batch of N900. Some users sometimes do seem to complain about problems that I never ever even encountered. And I need the charge my N900 at least 2-3 times a day due to the heavy usage. And I also currently only have 5% free of rootfs. I install a lot of apps to try from extras-devel. So my point is I certainly don't treat it well, but have never had major problems.
