I cloned the 2008Os on N800 to a 4G Adata micro/SD adapter and switched the micro to mini adapter and inserted into N810. Everything worked so far, everything, I have used it for 2 weeks. The thing I like about this way, is the two tablets looked and felt the same, made a habitual creature like me does things a lot faster. I do not have to retrain my brain to locate different programs and icons. And boy, to install every single little pet projects, and manually insert RSS feeds and videocenter URLs.... Hope this helps in your decision,

I did just this after receiving my n810. I backed up my n800 copied the backup to my n810 and did a restore. It worked as expected. My registered bluetooth items came in, my registered access points came in and apps were reinstalled. Only had the normall amount of manual work that comes after any restore.

I made sure to answer no each time it prompted me about overwriting a newer file.

As a side note it would be nice if the backup utility backed up all settings. I always have to manually transfer some settings by hand after doing a restore.

Based on couple success stories above I'm going to try this. Wish me luck...

UPDATE: I did restore my N800 backup on N810 and everything seem to work fine.
