I thought it's time for a little update on my experience with my new Vaio Laptop. Running Vista and KDE 4.2.3. First about the hardware. It's serously good. Right now I'm typing with the brightness on it's lowest level, yet it's almost too bright. I've even used it in the full sun already, and if the black casing wouldn't have gotten so hot with the sun burning on it I might have stayed longer ;-)
Secondly, I'm typing in the dark. So I can't see the keyboard, yet I didn't make any mistakes with that smiley above. Maybe I'm a great touchtypist, or easily impressed - but I'd rather think this keyboard is just amazingly intuitive. Oh, and logging in by swiping a finger - well, let's just say any geek would appreciate that.
Then about KDE. Getting it installed was a little challenge - the installer still needs a little work. Well, it didn't get one of the dependencies, and many of the servers didn't work or were outdated, the installer itself works just fine. If only it would pick servers automatically...
I've installed an Amarok nightly, and beta3 of KOffice. I must confess I miss plasma and KRunner (at least plasma is there but it's integration with windows is... missing...) but Explorer and I are getting along reasonably well. That app has some seriously powerful features, yet it's reasonably easy to use. The windows menu however is horrible (how can people complain about Kickoff if this is the standard for most computer users?). Luckily you can use it as KRunner - hit the 'Win' key, type and hit enter. Mostly works. As soon as MS fixes the windowmanagement (or lack thereof) I would probably consider Vista 'ready for casual use' ;-)
Anyway. So what KDE applications are a great addition to the MS desktop? I'd start with Okular. Adobe's pdf reader is an abomination, and Okular feels like a breath of fresh air. Kolourpaint is surprisingly similair to MS paint, except that it's not THAT anorexic in the feature department. Perfect replacement. And I often run Kopete, Konversation and Choqok in the communication department. Gwenview is a fine replacement for the normal Vista picture viewer.
As I said, Explorer is rather OK as a filemanager, and Dolphin, lacking some Vista integration, doesn't make a lot of sense as replacement right now. And imho nothing beats Chrome in the performance department so that's what I use to browse the web.
Unfortunately Beta3 of KSpread 2.0 doesn't work with most of my ODF presentations. I know the RC on linux does so I guess a later version will do better - and the final release is soon. KWord is fine for casual texts, and it can do more advanced stuff as well - but the interoperability with OpenOffice isn't great and some things are missing or work rather uncomfortable so I wouldn't recommend removing OO yet.
KTorrent works, and downloads just fine. Digikam - well, beyond starting it up I haven't used it yet. Thanks to a broken monitor I'm stuck to this laptop so I use it a bit more than usual but I still don't feel like working on it like I would on my normal PC...
All in all, KDE on windows works pretty well. It is an alien environment for the KDE applications, which sometimes shows, but generally they do a fine job. Performance is comparable to native windows apps and stability is reasonable. Personally, I still find windows a bit uneasy so I find it hard to judge how good it all really is, but with the KDE apps it feels a bit more at home for me so I like it ;-)
