"High-end enterprise environments?" The article is about scientific research clusters (MPP), not enterprise business servers, which are typically large SMP boxes. There's a big difference between 100 one-way Linux boxes crunching numbers with Fortran and a 100-way Sun E15000 running OLTP with Oracle. The latter is a "high-end enterprise environment"; the former is not.
The entire review really boils down to one statement: "It's not Linux". And it's not. Solaris is an enterprise OS--standards compliant, stable, scalable, extremely well documented, and well supported (both through free and paid channels). It has good performance management tools, too. It beats Linux handily in all of these categories.
These are things you won't notice immediately "out of the box", but you'll certainly notice them if you need maximum uptime for your mission-critical enterprise applications. If the factors I mentioned above mean something to you, then you probably already have Solaris in your environment.

Or perhaps (and I think more likely) you're compiling free software that depends on GNU extensions to C, make, etc.
