+1. A lot of people are using Stellarium on laptops/notebooks/netbooks
that don't support OpenGL 2.0, because they need something that they
can easily carry "in the field", especially for telescope control.

My main computer at the moment (and probably for the next two years)
is also a netbook that doesn't support OpenGL 2. So, dropping the
support for less-able graphics hardware will prevent me from
contributing to Stellarium. :)
