If I understand correctly (do I?) this whole ‘semantic desktop’ (Strigi, Nepomuk) thing is just for finding files. Or is not?
In that case it is definitely not for me. On rare occasions, when I want to find a file I use Kfind just like I did in KDE 3. It can search by file names and by file contents. When Kfind finds something, it shows file names and directories where those files are. No indexing, no other stuff which needs memory and CPU time. Perfect.
As for the KDE 4 PIM…
At the moment I use KDE 3 Kontact suite - Korganizer, Akgregator, Kmail. Most important for me is Korganizer - other parts can be switched to something else in any moment.
The only exception is kaddressbook. KDE 3 kaddressbook was too buggy (it hanged for a couple of minutes when I changed any contact - very annoying), so I migrated to KDE 4 Kaddressbook. It is not perfect, but without that bug. And addressbook is important for me too. So I cannot use only KDE 3 PIM.
The logical step would be migrating from KDE 3 Kontact to KDE 4 Kontact. But everytime I try doing it I just begin to hate it. Interface just became less informative. And more bloated. Literally. See for yourself: to-dos and events look like bubbles, old were rectangular. That’s ok. But with the same font size and same bubble size I only see one row of text, while with old rectangulars I saw two. That is big drawback if you are using notebook with small screen. I will fill a bug report, when I figure out how to clearly define the problem in text. So I will continue to fight with the windmills.
There is one more regression: there was an icon on recurring events (two arrows), now it is gone. One year ago (2009, 22 March) I have filed a bug report: https://bugs.kde.org/show_bug.cgi?id=187859
Still no answer. But I have bubbles! Nice.
I tried to work with Kontact 4 today and see, maybe miraculously something has changed in the settings and I can make everything look compact and informative just like in Kontact 3. But Kontact crashed 4 times while I was examing it. Well, that is not good.
That is why I feel torn between two versions of KDE PIMs. But at the moment I will stay with 3d version and use kaddressbook from version 4.
When Kaddressbook 4 starts it automatically loads all that ‘akonadi’ stuff, just like KDE 4 Kontact.
As I see in KDE’s ‘System Monitor’ it loads 13 new processes, which eat memory (and maybe CPU). Do I need all that?
I couldn’t synchronize Korganizer with Google Calendar or my Nokia 5800 with KDE 3 native tools. Though with not native tools - read Gcaldaemon - synchronization worked not very well. And I were not able to synchronize with Nokia 5800 at all (so now I do it through Google semi-manually).
Just a minute ago I have found a thread, where user claims to have Google Calendar and Google Contacts synchronized with akonadi:
Arch Linux Forums / Google calendar in akonadi
If synchronization works, then akonadi may be very useful for me. So akonadi = synchronization. Even better would be direct synchronization with the my Nokia 5800 phone, without using Google as an intermediary. I vote for akonadi.
And about the whole KDE 4 desktop…
Sometimes I feel that I am not the “target audience”, like martin_helm said.
But I tried to fight with Plasma and make it do, what I want. And I succeeded. It was a painful process, but finally I managed to tune my desktop through manually editting plasma configuration files in text editor:
Post #27 - 11.2 and dual monitors - openSUSE Forums
Later I even managed to install special plasmoid for toggling panels visibility (I have 4 panels). And, what is strange, it works! Even better than in KDE 3.
Now it is nearly perfect. So until something breaks (or, maybe, Kontact 4 becomes better?) I will stay with KDE 4 using KDE 3 Kontact. (And Bluetooth stack from KDE 3. KDE 4 Bluetooth still lacks obex:// as far as I know and has problems with sending/receiving files).
Gnome? Well, not for me…
