+1. This is why KDE has been my favourite desktop for 10 years. I don't do fancy stuff on my computer. I code. KDE gets the basic, essential tools right. Dolphin is better than Mac's Finder, Windows Explorer and Gnome's equivalent. And so is Konsole.
I hope KDE keeps going strong.
I think KDE's biggest problem is that it lacks developers and other resources. And the few resources they have are regularly wasted on rewriting code, adapting KDE for failed tablet projects, and well moving KMail (once the best mail client) to a system (Akonadi) that uses MySQL and some RDF database. Which is like the most useless combination.
Why would anyone think that using MySQL to locally store metadata for emails would be a good idea? It constantly eats your battery. And I highly doubt that any individual person receives enough mails per minute to require MySQL to handle the metadata. Which Akonadi couldn't even do anyway because the RDF database just absolutely kills scalability. I've tried to delete a few hundred mails and the RDF database went berserk. So why even bother with MySQL then? They've now replaced the RDF database with a simpler replacement they've wrote. So maybe it scales a bit better now. And maybe in a few years they'll figure out that the whole MySQL thing was a stupid idea and replace that with a simpler backend.
(Oh, and it doesn't seem to properly support IMAP IDLE, at least I can't tell KMail which folders to watch...)
