I only use OneDrive because I got a free year of Office 365 and a terabyte of Onedrive storage when I bought my Surface Pro 8. I’ve since become dependent on it (I tried writing with OpenOffice and LibreOffice and hated both). When it came time to renew after the year was up it was 50% off so I renewed. Something like $60 for a year. I don’t even have that Surface anymore.
The nice thing about working from the cloud is knowing that if my house burns down, or it floods, or gets robbed, or whatever, I will still have the newest, freshest copy of my work. On the off chance that something takes Microsoft down I’ll still have my local copies that are a week old at best. Now, if my house burns AND Microsoft goes down, I’m screwed. Wait, no, I still have my stuff on Tapas, so not all would be lost!
