Upgradecenter heeft een review van Caldera Open Linux 1.3:
There are many great features about a Linux operating system. Probably the most common one is that most distributions can be obtained free of charge. The one drawback to that is the lack of documentation and support if you need it. The other big thing is the source code, most versions of Linux if you know anything about the system and/or programming can be recompiled to really meet your custom needs. The uses for Caldera Open Linux right now are virtually endless, there's programs being written and ported to it every day.
