Just remember all the people struggling with open office (not relevant because of google docs and alike) and video/audio codecs (Spotify, Netflix etc).

You can call me an old curmudgeon if you like, but I just don't trust the Cloud for storage. (Ever since a badly configured DropBox instance removed around a gigabyte of files.) So I insist on keeping all my Documents at home on my main system, along with all of my 'write once, keep forever' files.

In my early days, I tried to maintain the ability to use MS Word documents as they were all that was circulated in the 90s and early naughties. That included the use of WABI and other kludges. But with the later advent of ubiquitous .PDF files, that pressure for MS Office compatibility has disappeared. Consequently, I find I need only Libre Office Calc to do my spreadsheets, and Libre Office Writer to do my text word-processing. They can do everything I need.

When you say "App Store apps", are you talking about the packages managed by package managers like Synaptic which is used on Ubuntu/Debian/Mint/etc. ?
