I know my wife wanted a windows computer specifically for Excel. She did not realize it costs a good deal extra, so was delighted when I installed LibreOffice. (Other computing devices are kindles. Had a chromebook for a time.) So, there is still some desire for the basic programs. I agree that LibreOffice is more than good enough for the task, though.
I don't think I could handle Explorer to support my workflow for managing photos. And it is a simple workflow. (First, copy everything over, then go through "flagging" all pictures I like, then go through flagged items and trim duplicates or ones that just aren't as good, finally basic color correction and upload somewhere for family.) I confess the shotwell program is not the best. Though I can not say what it is I don't care for on it.
Glad to hear the printer situation has improved. I just remember having more success with my Linux machines on just getting something printed. To the point that it was highly frustrating that it would not just print in Windows.
Sorry to hear you have power management issues. I don't think I have hit those. Though... I also do not make regular use of hibernating a computer. What is the main advantage of that?
