KDE is way too buggy.
The argument:
If you are like me, when it comes to computers you want them to just - work. For the past 7 years of my using Linux, I've always tended towards Gnome, because unlike KDE it was simplistic and always seemed to 'just work'. Sure - I had my share of difficulties with Linux, stuff thats kept me up til the early hours of the morning, but recently with Gnome3 I just couldn't take any more.
The Problem with Gnome:
My computer usage is twofold, reading and watching. If I'm not on the forums, I'm watching some documentary put out on Youtube - or some rather naughtily downloaded TV show from America. But with Gnome3 everything I watched seemed to stutter. At first I thought it was VLC, and I made excuse after excuse because I loved Gnome 3, it may be the most beautiful OS I've ever had. But I couldn't cope any longer and downloaded Neptune 3.1- A KDE distro.
The Problem with KDE:
From install - I got a segfault. By the time I lost my rag, I had no sound, and I couldn't even delete trash-1000 from my USB drive (I had to copy and paste everything onto my desktop). I have far too many programs, some of which are next to useless. Upon install I had no apt sources list. The only thing that was better than Gnome and not drastically worse - My videos didn't stutter anymore.
Put simply, I don't know how anybody uses KDE, it is the most awful desktop environment I have ever used. Maybe its Neptune's fault? But I doubt it. I am now hoping that Solydx Debian XFCE will solve my issues (issues I spent 2 days on, and am no linux newbie) But either way, I will heave a sigh of relief when this awful, awful thing is off my computer.
The Conclusion:
I have used Linux for a long time, I started by trying an out-of-date DVD with Fedora 4 on it, I was quite out of my depth, and when I tried to update it threw a long list of errors at me. I quickly realised the issue, and installed something else (can't remember now). My computer only had 128mb of ram, and so I couldn't install ubuntu. I often used puppy, simplymepis 6.5 (which is the best iteration of KDE I've ever used). Eventually i upgraded my laptop, and put Linux Mint 7 on it (which was probably the best iteration of Gnome I've ever used). Of course I've used far more distros than listed here, but I just wanted to give you some idea of me not being an idiot.
I for one will spend many years avoiding KDE until it matures. As perhaps the oldest Desktop Environment in use today, I'm disappointed at its consistent crashing, its half-cocked widgets and its ugly themes. Someone somewhere must break it down to its basic components, and sort it out.
Comments
Yes the Plasma widgets are a mess, and very buggy. Half of them don't even install, most of the others have bugs and/or usability issues. I asked on the KDE forums where I could find the source for one of my favourite widgets so that I could fix the bugs myself (because I could not find it anywhere on the web), but no one replied.
I think it's safe to say KDE is a dead-end. I'm not looking forward to switching to another desktop experience and re-learning everything from scratch.
