i dont have a blog but i want to bore you the same with my theory:

if nokia announces (and decides) that it will come to n900 that will break the agreement with sygic. if announces (and decides) that it wont it will piss off a lot of people just a couple of days before the apple event.
and more important: a symbian phone, today, is a smartphone for dumb people. problem is that dumb people today buys iphones. and more dumb people will buy iphones in the future, in a few days we will see iphone 4 and all. nokia must give dumb people something cause theres plenty of unsold n97 out there.

then n900 is almost sold out everywhere. and certainly nokia doesnt need to push it right now. im pissed of about this but im not gonna sell it either. and nokia doesnt need dumb people to buy n900. too much cost for support, and it would ruin the product image.

obviously its just my theory
