Thank's everybody for tips and todo-lists for making Note experience better, even though I wish we could have Real Linux in this great HW. I have been especially using Kangal's advice on updating my note. Keep them coming.

A word of warning, yesterday I tried updating HydraCore kernel with CWM, and got problems creating Nandroid backups. I just could not get working backup when running HydraCore. When restoring, either MD4 sum failed, files were missing from backup, or rebooting got stuck in flashing "SAMSUNG" or "android".

I got back GL_NOTECORE_v14-1_STD with stock ICS 4.0.4 from backup and don't seem to have problems with backup/restore anymore.
