Yeah got it and tried it. I am posting the my results below.

First your desktop:


My result:


ANALYSIS
While creating the script, I forgoot about backing up the QBW images so all the QBW widgets now dont have images. So that has to be done.
Secondly, can you post here the rest of the desktops? Coz out of 8 desktops, one of them is completely empy. Was it filled with contacts? My script does not save/restore contacts for obvious reason.
Then the icons and fonts. I think what can be done for this is, the app should store the name of the icon-set/theme/font used and ifit is available in the destination n900, it should apply. Else, maybe it should give an option to download it? What does everybody think?
Finally, the individual widget settings like for qflipclock, email, calender, rss etc. This is think i will do only stage by stage and is not a priority.

Have I missed anything?
