I thought this was rather interesting as it reflects partially what is being said repeatedly in the data analysis of my open source research project. While this is nothing profound, or unexpected, people, especially adults, have trouble moving to the Linux desktop because “it’s different”. However, making the interface more similar to what they know and expect may lead to greater adoption.
Fedora XP or “How I Got My Wife To Love Linux” demonstrates how even minor Linux modifications such as simulating the Windows “start” button (although my firm belief is that the Windows start button was never natively intutive, only intuitive by massive social repetition) could lead to wider acceptance of desktop Linux.
From my own experience and research, I know that this familiarity factor is very relevant to wide-scale technology adoptions in K-12 education. As a generality, teachers don’t like and will resist change. Making technology intuitive may not always be enough … familiarity, at least in the short term, may sometimes count for more.
