Re: At least is isnt oracle or M$
The OS is from Linus and chums, Redhat adds a few storage bits and some Redhat logos and erm.......
From a customer standpoint the main thing RedHat adds is formal support. There are still a lot of companies who are uncomfortable deploying an OS that has product support only from StackExchange and web forums. This market is fairly insensitive to price, which is good for a company like RedHat. (Although there has been an exodus of higher education customers as the price has gone up; like Sun did back in the day, they've been squeezing out that market. Two campuses I've worked for have switched wholesale to CentOS.)
