Here another "KDE4 is really usable" blog. Well, I just want to point that out up front. Oh, and my day was different from Wade's. Yesterday I gave a talk to dutch students about KDE 4, I didn't get machette's to my head. Aaah well, everyone's different.
The real topic is something else, though - I wanna know who did the following:
That person deserves some kudos. I haven't seen any blogs or whatever about it, but I think it's a great job. Solid Usability Work the KDE Way (tm): make it easier to use and more powerful at the same time. Yes, it's a bit harder, but much more rewarding to not take the easy route of 'dumbing down'. Nice work... Of course, there is more to do, maybe the person who did this can spare some time on the 'edit toolbars' dialog as well.... Currently drag'n'drop is broken ;-)
Another thing which I wanted to mention: Cornelius said he was amazed by the speed of KDE 4 apps. Now I took that with a grain of salt, as I hadn't seen any amazing speed yet - Okular was slow, I had seen konqi using 100% cpu and still stutter on scrolling, KWin didn't exactly go smooth... But while making the above screenshots I used kwrite, and indeed - kwrite4 starts faster (feels at least twice as fast) as kwrite3 (both in my kde3 session)! And other apps do the same. Gwenview is like 10 times faster, and konqi4 seems faster without pre-loading than konqi3 with! Konsole seems a tiny bit slower, though.
Sure, you don't want kbuildsycoca4 to run first, but after that's done - applications are wonderfully fast. It's like someone turned 'speed' on in Trunk, somewhere in the last week... Whoever did that, nice work!
Now, the last thing: colors. I've just been trying the colorscheme things, and they work great - see the following screenshots (yes, the second one, called Beos(?), gives the higher contrast many ppl seem to want from Oxygen).
The oxygen style also does a pretty nice job on darker colorschemes (unlike most KDE3 styles):
