Speed. Simplicity. All you want to do is update a single value or insert a row into a spreadsheet? You can probably be done using the terminal application before Excel even finishes opening.
On my computers, I use Excel so rarely--around once a month or so-- and do full reboots so rarely that it always interrupts me as soon as I open it to finish applying an update to office. And of course, since I'm on Windows, Excel has locked the file (usually just a csv, but one with a dozen or more columns, so hard to do with a text editor) so nothing else can open it in the meantime, and I have to wait several minutes for the modal popup to go away before I can finish appending a timestamp to the end of the file.
