Sending N900 back to Nokia

Tomorrow I will send my Nokia N900 back to Nokia.

But I am not abandoning that platform. It is just because my N900 has few dead pixels on screen. They are grouped in area of “task switcher” button so were harder to notice.

Are those bad pixels or just dust? No difference for me as in both situations they are visible.
