An area where Linux is sometimes criticised is the level of difficulty expericed by people new to the operating system when installing software. Earlier today, Dr A J Cann posted an example of this criticism when he suggested that Ubuntu should follow the same model of software distribution used Microsoft Windows and Apple Mac OS X of having a downloadable installer file for your desired program. I don't agree with his suggestion, but do see his point that installing software for someone unfamiliar to Linux can seem a daunting task. If I know someone is about to try out Kubuntu, I always try to sit them down and explain the package management system to them. There is no direct equivant of this on other operating systems, so I find it helps to explain it to people. Once, somebody explained package management to me and it saved me a lot of time.
