An SSD (Solid State Drive) will really speed up your computer. It will significantly reduce the boot time and increase the response of most software applications.
Every write action to a SSD will result in the undesirable phenomenon known as write amplification. This may shorten the life of the SSD.
Ubuntu 16.04 seems to be ready for SSD drives. Here are some steps you should take to extend the life of your SSD drive. The keypoint is to reduce write actions.

In a previous post it was described how to setup and monitor a UPS dedicated to your Ubuntu workstation computer (STANDALONE mode).
In some cases you want your UPS to protect more than one computer (MASTER-SLAVE mode). apcupsd is a great solution in case of APC UPS. In my case, I use an APC UPS ("APC Back UPS BR1500GI RS 1500VA (LI)") which is physically connected via USB with an Ubuntu file and backup server (host name atlas, IP 192.168.1.52 - the MASTER computer). But I also want my UPS to protect my Ubuntu workstation (host name athena, IP 192.168.1.51 - the SLAVE computer).
UPS means Uninterruptible Power Supply. The UPS is a device which has a rechargeable battery provides electrical power for a few minutes after the outage, depending on its specifications. However, UPS is not a power generator and its mission is NOT to continue the operation of the computer for all the duration of the blackout.
Power Management module on Ubuntu 16.04 is a flexible tool to manage your computer UPS. If you have a UPS dedicated to your workstation, Ubuntu "Power Management" is all you need.
Virtualbox is an advanced virtualization platform. It runs on Windows, Linux, Macintosh, and Solaris hosts and supports a large number of guest operating systems. It is available as Open Source Software (GPL2). It is lightweight and actively developed, so it is suitable for use in workstations.
I use Virtualbox to create virtual machines mainly for testing:

Clonezilla is a Free and Open Source bootable GNU/Linux distribution for disk or partition imaging and cloning. There are two versions available:
After installation of Ubuntu Desktop 16.04, a nasty surprise awaits you. Mouse is very sensitive (practically unusable) in most systems with wireless mouse. Probably, this will not happen in systems with old wired mouse. Trying to fix mouse sensitivity, using System Settings → Mouse and Touchpad, you will see that it is not possible.
Fortunately, there is an easy way to fix it, using xset (user preference utility for X).
Ubuntu Desktop releases offer handy GUI utilities to handle Package Management and System Update:
Using a desktop computer (workstation), it is more possible that you will use these GUI utilities. However, you can use the command line if you prefer. It's a matter of choice.
It is recommended to select a Long Term Support (LTS) Ubuntu Release for your Desktop Workstation, so you will have Updates for 5 years. A new LTS version is released every 2 years. Current LTS release (2016 Oct) is Ubuntu 16.04 (Xenial Xerus).
After installing a new Linux kernel, old kernels are not automatically deleted. They remain in your disk (/boot partition). You have to delete them manually. Why?
The main reason is to save disk space, which occupied by old kernels. Some systems may become unusable if not enough disk space is available in /boot partition. However, disk space is not a problem in modern systems.
You will never delete your current kernel, of course. It is recommended to keep at least one or two older kernels, so you can boot your system in an emergency situation (hardware or software compatibility issues with the current kernel).
