RHEL Vs Sun Solaris

Today, I received a mail from Sun Micro systems promoting Solaris 10. It is a web cast, and the link is here Check it out. Nicely done web cast, but i am a little skeptical about how Solaris would shine against Linux which most of us geeks are more familiar with. Yes it might work for organisations, but when individual users are taken into account, the learning curve is a little higher than learning Linux.
