1. Internet WiFi is smooth.
2. Firefox works effectively.
3. LibreOffice is new but I do not like it's dark theme (that could be tinkered with when using).
4. I use AbiWord exclusively for my writing. It's page layout is excellent. It is most likely in it's repository.
5. I did not try software installation.
6. Installation is streamlined and altogether new look
7. It's is huge 5.2GB and my Linux file system cannot cut and paste the image outside 4.3GB. Having written it in a 8GB USB stick I have to delete it .
Thank YOU Ubuntu guys and girls.
