Upgraded Asus 1001P to Xubuntu 16.04.1 from 14.04, automated path left errors, so reinstalled on top from USB key. Also upgraded Lenovo 8258-HBU to Ubuntu 16.04.1 with XFCE4 desktop, so spouse’s interface is more similar across multiple computers. Older computers with 2GB of RAM are still going strong with Linux, dual boot shows that Windows upgrades would be hopeless.
