In terms of desktop I disagree. 10gb of memory on a Windows 10 VM was not enough after 2 days of working. The only apps I was allowed to use were firefox and outlook. Thats it. I couldn't open more than about 4 tabs. Most of the tabs were Google based. I used to have to close tabs and reopen them between spreadsheets just to avoid the lockups. It took hours just to work with some spreadsheets. This isn't anecdotal btw, it was a lack of system memory causing performance issues and app crashes due to greedy allocators. Closing apps out regularly helped but still a pain.

If 10 y/o software was running on a 10/yo machine I might agree, but now the bloat is just asinine. 

Smart phones I think less so, only because I'm still rocking a 6 y/o device thats been heavily striped down and only has 8 usable apps installed.
