So I’ve started using a Desktop computer recently at work. I didn’t really want to mess my laptop’s OS with monstrous development tools like Weblogic, Oracle. Plus these sort of tools require a very powerful machine (even 3 gigs of RAM is like a minimal threshold). I made Kubuntu an OS of my choice.
What can I say after using it for a week? Very nice, really user-friendly OS with excellent packaging system and an interface based on KDE. Plus it’s still Linux – nobody had canceled CLI interface (in case something goes wrong)

Should’ve gone with Mac OS X. That’s the OS of choice of our new developer.
