It seems strange but if you watch closely maybe major pieces are coming together before our very eyes. Linux is a big puzzle and the pieces are coming together. First we have Ubuntu Intrepid Ibex releasing this month. Gnome 2.24 has been released with big improvements in instant messaging and video/audio conferencing. Gnome is also bringing to the table a mobile platform, tabbed file browing, and improved screen resolution controls(which I think have been long overdue).
Many popular applications well known through the linux world are producing quality updates like Gimp, and are becoming increasingly comparable to high end software.
And the biggest reason I can see linux evolving and growing is that fact that I'm positive I wasn't the only person to get another new comer to try linux yesterday!
