Sorry, but the N900 is NOT "smartphoner" friendly and I have been warning about this for a while in regards to their assumptions. I also warned that as more people get the N900, these type of posts will increase. The device is still constrained with supply- you all have not seen posts yet compared to what will come:

Here are samples that will come from the smartphone crowd and some posted by people that actually like the device- a mix of legit and trivial points:

1. Where is MMS?
2. Where is portrait?
3. Where are the apps?
4. Wifi and GPRS issues
5. Battery problems (I think this is mainly due to Flash)
6. Codec issues
7. Media player issues like playlists
8. GPS problems
9. Emulator issues (not as good as WM or Android options- yet)
10. Stuttering video at start-up
11. Youtube stuttering and HQ not as good as other devices.
12. People messing their N900 up due to installing out of "safe" repositories.
13. Apparently weak USB connector
14. Weak 2G reception for low areas
15. Blurry flash photos
16. Problematic auto focus
17. MP3 player can be a stuttery mess when browser is open and using it.
18. FM radio signal is weak
19. Where is the file indexing? The OS seems to refresh everytime you open a directory.

These are just the things I thought of in a few minutes, but all have some truth to them to at least a trace level. If just perception, the point is the issues are perceived as problems.

If the N900 was targeted to smartphoners, it was released too early and should have been more oriented to a consumer level device.

The N900 seems like a beta device to me- kind of like the G1 was for Android, but the G1 at least functioned really well as a smartphone. It sucked for about everything else when launched.


Added:

Another point is some of the fanboys will only drive people away from the N900. As luck will have it, some of those people could have provided contributions to the community down the road. A constrained user base tends to not be a good thing.
