I am pretty sure n9 with maemo will be the device, the os, that will last longer than other did. And it won't be only n9 which will have new Meego but at least one more(I can expect two more but not more than that) device with meego will be released in 2011. Those who got n900 are kind of left behind but that won't happen to n9 and commercial developers will be interested in n9 as well as other meego devices as well. I just hope they would give another 50000 reasons to develop app for n9. But its totally my own opinion, and I may turn out to be wrong later on.
