Most users ever online was 2,726, 05-26-10 at 20:31. (PR 1.2)

I would still want to know how many total n900s were produced
(as well as how many were sold)
and how many were upgraded to 1.3.
These things would tell a lot about who we are:

There are those who use handphones.
There are those who use smartphones.
Then there are those who use the n900.

Cheers
