While we wait for KDE CVS and KDE mail to be resurrected, Hetz wrote in with a pointer to .dep's impressions of a pre-beta2 version of KDE3. It's actually quite positive (he finds KDE3 stable already), with screenshots, but also not without some criticism of KMail changes and a good point about the difficult-to-kill KOrganizer alarm daemon.
The only other thing that made me react was the drastic new semantics of Klipper. As a KDE2 user grown attached to Klipper and its quirks, I'm a bit apprehensive about the change in behaviour that's been forced by Qt3. On the other hand, many people from X Clipboard Interoperability land have long been clamouring for this change, and I'm sure there's a way to get Klipper to revert back to its old behaviour.
However, Klipper may now be less than useful in its default incarnation considering that most of us don't want to know a PRIMARY selection from a CLIPBOARD selection. Consider Konsole users too, who now have to go out of their way to get a selection into the default Klipper.
Oh, and before you get too excited, remember that KDE3 beta2 has not yet been released, let alone the final KDE3.
