Life Saver
I am not a Linux GURU. I have been an MS Pro since the early '80's (Dos 2.1).
Just as sure (not IF, but WHEN) as California is going to slide into the Pacific Ocean, so will MS.
With UBUNTU, I have the ability to set up a separate partition or drive on any of my MS Units with UBUNTU. (Exception - MS has sabotaged this possibility with Win 8 - still can be done, but only with sophisticated work-arounds - not recommended for the less-than- highly proficient)
When MS eventually fails (or I become totally just fed up with it), I just boot on my UBUNTU partition and continue working.
Remember, the Internet ultimately runs on UNIX, not MS. Linux (UBUNTU) can be described as a form of UNIX and thus very compatible.
UBUNTU can read your MS partitions and all of the files therein (not vice-versa)
UBUNTU comes complete with equivalents of most programs generally used on MS units. This includes an Office Suite (Libre Office), a browser (Firefox) and numerous other programs. All are regularly updated as required.
The only cost associated with this is your time to set it up ( I'm sure that donations will be graciously accepted - be generous - think about what MS has done to you over the years)
----------------------------------
OK, this is what UBUNTU has done for me. I am not sophisticated enough in this area to intelligently evaluate this against other Linux based systems. Obviously, their targeted purpose group may also be different than my priorities. But for me, at this time, Thank You, UBUNTU!
