I have now played with the SF release for some time already.
Not as a daily use but some hours a day.
Also I have upgraded it every day with zypper using enabled repositories - is it a correct way or is it better to install a fresh daily image as they appear?
Some remarks in addition to known problems on the basis of yesterdays zypper update:
1. It is very easy to miss a call - probably due to lack of performance.
2. top reports that about 80% of CPU power is idle after power-up. From that X takes 10%. In comparison - maemo has 95% idle in the same conditions.
3. vkb does not appear at all
4. e-mail application is missing but is startable from the command line. It is possible to create an account and send&receive messages, but only inbox folder is shown - no sent etc.
5. kasvopus is started in full screen and I did not find a way to get out of it - had to reboot
6. in picture viewer it is impossible to scroll to the bottom row of thumbnails - they are hiding as soon as the finger is released from the screen.
7. it puts time 3 hours back - it seems to assume that the device is running UTC without time zone&DST (Europe/Tallinn here)
8. Opera is quite usable

And many thaks to the N900 meego DE team for their efforts
