I suppose that depends on how reliable is the incremental flash process. If it's 100% then there should be no problems with what you suggest. 

My only concern would be getting into a Windows XP-like situation where you reinstall with XP SP1 becaude that's what came with your system and then have to install SP2 and 100+ hotfixes to get back to where you were.

Microsoft have put a lot of effort into windows update to get around the fact that they can't redistribute windows CDs where with the N770/N800 we're in the reverse situation where redistribution of the firmware image is relatively painless.

It also occurs to me that when you reflash, you know you have to do a backup or you lose your data. The fact that when you boot for the first time with a fresh image, the N800 sees the backups and offers to reinstall your settings makes that a relatively painless process. 

But if you can just apply a major firmware upgrade by accepting it in application manager and you don't think to backup first, what happens it goes wrong leaving you with an unworkable system?

Andy, voting for both the old and the new approach...
