+1 for same here. We're aggressively moving off of any & every Oracle platform, mostly because of the cost they've come back to us with to continue using their software & hardware, but also how inflexible they are with the whole process. Mind you, we've been a long time Sun customer, and had as such had a very favorable relationship with them, so the cost is more of a shock to us than someone with a more heterogeneous environment.
It's unfortunate for a lot of the people & products with extensive experience and development interest in Sun/Solaris. In my eyes, Solaris is a true enterprise grade OS. I think the OS industry as a whole is very lucky to have Red Hat made the progress it has over the past few years. They're slowly moving from a linux on commodity hardware strategy to enterprise level products and resulting development. Before a few years ago, I'd be reluctant to run linux for something really high-end, however they're now powering the infrastructure for the NYSE. That's a pretty reputable feat. Rumors of ZFS porting to RHEL are out there, and they've improved greatly on their clustering and virtualization offerings too. Red is the new purple.
