I can only speak for the UK but I have noticed the N900 maybe a bigger hit than Nokia were expecting.
With all the hype of Smartphones in the media but the iphone to be replaced in the summer putting off a lot of people from buying and the nexus one hard to obtain at least for everyday users in the UK and elsewhere. The N900 may have a window where it considered by many everyday users who want the highest spec smartphone avaiable..

Hopefully this will force Nokia to invest time, effort and money in the N900. Maybe they will learn a good device now has a longer shelf life. With people having 18 and 24 month contracts in some cases software will become more important. As the Iphone and android have shown. Nokia when announcing OVI were hinting at that services were where the money is.

Plenty of N900 Users will be prepared to have an easier life with easy to install apps and possibly whole suites of software so their device can be modified to suit their needs/intrest. Which is im sure will turn Nokias head..
