Re: Office 365
"I would rather use a traditional desktop version"
Every time they break O365 during an "update" or your broadband goes down you get stranded without your data.
On top of which, W2019 (or whatever desktop version) and your files are yours for life, whereas if your O365 subscription payment fails (e.g. you bank with TSB) you lose all your data.
On top of which, using a desktop version you're not sharing your files with a potentially interested third party with more legal clout than yourself to do as it pleases.
On top of which, promotion of continuous update as a benefit merely emphasises the need for constant fixes to a flawed product.
