[ubuntu-za] Upgrade to new Ubuntu OS every 6 months?

[Anton Binedell]

Hello,

Thanks for the help with my last dilemma.Ubuntu is now running as my
only OS. I however have an open question about how users upgrade on
Ubuntu, do you upgrade every 6 months to a newer version of Ubuntu or do
you stay with the OS until the end of the OS lifespan (18 months)? And
what would be the best option: upgrade every 6 months; 12 months or 18
months?   

Regards
Anton
