Newbie chiming in here, this is my first non-windows machine. Owned my N810 for about 3 months and need to say something. I bought this device for a few reasons:
1. The Nokia brand name to me means trust and quality.
2. The built-in apps is exactly what I was seeking in a small package.
3. Wanted a media player that would be an improvement over my WM5 Pocket PC.

I'm disappointed in the built-in apps quality. Other then the browser and wayfinder, everything else seems to have issues. Items that don't work well "out of the box":
1. pop or imap email
2. video formats
3. lan connections, streaming and file transfer
4. finger keyboard

To be blunt, if I knew then what I know now I would have not bought the N810. But would have considered a N800 with OS2007. It worries me that the OS upgrade seems to have added more problems then it fixed.
Let me say that I'm not a "workaround" kind of user and like to stick with the apps that come with the unit when new. Plain and simple, they should work. Not all of us are nFanboys.
I feel that Nokia should have done more testing before releasing the unit with an OS that does not work well.
I'm going to keep the N810 until after the next OS release. Email and finger keyboard need to be fixed, otherwise I'll let the unit go.

nFanboys can attack complainers but it will only hurt the whole Linux community in the end. Nokia needs to better support the IT community otherwise they will drop the product line if newbies leave the platform out of frustration.
