Does anybody have anything to add to these observations?

To confirm?

To dispute?

I will add another item to the list: migrating KMail files from KDE3 to TDE changes the index files. The change is non-destructive, annoying only, but KMail complains if a person tries to use KMail in both environments. Users can run KMail in either but must manually reindex all of the files each time.

Do we want to bother with making sure KDE3/Trinity can sit on the same PC? KDE

Sorry, 

this new gmail interface is rather annoying and cuts my emails off frequently. I think KDE4 is a higher priority.

We could change file names. Especially during our renaming process. I don't feel that Tonsole (sounds like a body part hehe) would work, we could rename it konsole-trinity or tkonsole? for other apps though, it could be smooth. Tsysguard T3B, TMail TAlarm... etc
