A little caution. Technical arguments (e.g. more translations/user base doubling every X months) could outdate. An argument without evidence, is just a claim.
RHEL4 is a far superior server product to Windows and a leading server product amongst UNIX distributions for good reason. So lets have some respect for what Red Hat has achieved in this industry.
- Not required to pay for security updates
- There is no required license fee
- There are no non-required license fees either
- No charge in perpetuity - that is a fundamental business principle of Canonical. Ubuntu is not charged through a subscription as many other Linux distributions are.
- Because Ubuntu has no restrictive software licenses associated with it, anyone can copy and redistribute.
There is more than one company that provides commercial support. See http://www.ubuntu.com/support/marketplace
Industry support from IBM for DB2 http://www.ubuntu.com/news/db2cert
- some questions for which we have no answers yet - such as official support from HP and IBM on their hardware : and be sure that this something that all of the competitors will ask our customers / users.
- Canonical depends on its channel partners to deliver service and support to end users and businesses running Ubuntu. It does not have to manage channel contention.
- Mass deployment options; Preseeding vs Kickstart
- Does Ubuntu have a web-based management system comparable to Webmin?
- The leading package management system, APT.
- More developer friendly. Ubuntu has rails.
- Ubuntu has three official flavors ( soon to be 4 ) and offers real choice to users. e.g. Edubuntu
- Edubuntu is uniquely targeted at junior schools and is creating interest around the world.
- Edubuntu has LTSP at its core, and is tightly integrated to make thin clients easy to manage for schools in particular
- Flexibility - no worries about changing Ubuntu for personal or company needs to make a derivative distro for specific requirements.
- Ubuntu users have access to the largest variety of FOSS through worldwide mirrors carrying Ubuntu and 17,000 plus application packages
- Larger community. More users. More checks. Better quality.
- Debian based, though with driven manual checks instead of time based QA
Netcraft Survey http://news.netcraft.com/archives/2005/12/05/strong_growth_for_debian.html Though that's for Debian stable. Not Ubuntu. And Red Hat still maintains leadership.
- A larger pool of active developers producing up to date code quicker through the Debian community
- Better translations to help developing countries and markets provide a truly localised and usable Linux
- Ubuntu has a user base in 215 countries worldwide : supported through a very efficient distribution system, enabling OSS benefits to be had by everyone.
- Ubuntu's user base is doubling approximately every 9 months
- Ubuntu has access to many hundreds of testers around the world and this feedback is incorporated into the releases
- Available to anyone for free through Shipit, a free CD distribution service
- Some statement by Mark?
