I don’t mean system stability, that is a given with Linux, but developer stability. Can I depend on this distro to be around in two years…in five years? How is the project funded? Does this innovative project have a large development community that can step in should the lead developer become ill or takes a lengthy sabbatical?

Neowin reports that internal builds of the operating system currently sport a one-click upgrade feature to update from one build to the next.

Having a consistent and capable editor available on any system is important, especially important for people who move from machine to machine for whatever reason. People who administer UNIX systems or who help others with their operating system (like many Linux User Group members) need to edit files quickly. The family of editors known as vi (including nvi, aka. vi on BSD) is very useful for this. Some of the reasons for its success are the use of classic UNIX philosophy, regular expressions, keyboard use (no mouse required) and plugins. The learning curve is a bit steep for beginners. Because text editors are written for use in terminals they can be used even across platforms with the help of fink (brew and others) on Mac OSX and cygwin on Windows. Text editors are clearly not WYSIWYG word processors.
