The new OS/firmware seems better to me in most of the ways already described by others. With a backup and restore, the whole process took about 1/2 hour -- mostly because the "claws" mail program had to be reconfigured from scratch.Upgrades of my old palm lifedrive were so much more painful.

With the previous os, my N800 had to be reflashed three times due to the perpetual reboot problem, so
maybe I'm just really good at reinstalling. I do keep copies of all my application
packages on one of my SD cards to make the process go faster.

So far, I haven't noticed any negative changes, but even though I use my N800 a lot, I really only use a few of its capabilities. ( rss feed reader, opera, mediaplayer, pdf viewer, gizmoproject and claws ) Perhaps this is why I don't have anything negative to say about the upgrade.

I know this is really minor, but I really appreciate the change in the RSS readers icon since now it's easier to distinquish from the file browser, etc...
