Most desktop computers at the NOT are 4-6 years old. Many are on the limit as for data storage, while the computer power (CPU) can not be upgraded (due to technology changes), and will need to be replaced. It is also planned to change the standard Linux operating system used in the computers. We have been using Ubuntu for more than 8 years now, but certain policy changes on this distribution are making it less attractive for our line of work. To not require major changes, we intend to use similar system (potentially, Linux Mint, an Ubuntu derivative). As a test, the laptops used by visiting schools have been reinstalled using Linux Mint, with satisfactory results.
