I think we can agree.
Solaris is the best for legacy products,
Linux is in the future. Linux can work hard to get back and give better
support for Legacy products, or it can go on and expect the
modernization of the commercial products which will eventually perceive
the security problems which Linux is already resolving (AFS for ex.
instead of NFS).
I prefer the second version: Linux is a Research Product.
