I have been using a Debian/Sidux/Kubuntu combination for some time (Debian for at least 3 years) but of late I have tired of the slow release's (hence the use of Kubuntu and the excellent Sidux) and their attitude towards KDE 4. However, I love having a rolling release model and the brilliant package management.
So after much thinking and looking around at what other Distros have to offer over Debian I took the plunge and installed Arch Linux at the weekend.
I have so far installed the base system and installed the KDEMod (now know as Chakra) packages. I installed it onto an old Thinkpad (p3 1.4, 256mb, 40gb hhd).
So far I am very very impressed. The feel of the KDEMod packages is very fast and responsive and so far I have not experienced any crashes. I would be interested to see what the standard Arch KDE4.1 packages perform like.
I found it very straight forward to install (although I had no wireless to worry about). I also leant a lot about the boot process and config of the system.
Why did I choose Arch over something like SuSE or Mint or any of the other distro's in the Distrowatch top 10? Well I wanted to keep the rolling release model and the easy package management, I wanted a distro that actually seems to be behind KDE and I wanted a system I could learn something with. To be honest my dream distro is Slackware with a decent implementation of Apt thrown in. If that happens I would be on it like a shot. Anyway Arch certainly is filling my criteria and I have read a great deal of good things about it.
I will play some more this week but unless I find anything I can't make work or, like, then for the first time in over 3 years Kermit, my main laptop, will run something other than a Debain based system.
