What I posted a year and a half ago AND three years ago still stands today... (copy-pasta follows)
Potentially Unpopular Opinion: the Microsoft 365 Family Annual Subscription plan is a fantastic deal if you have a lot of family members, and devices, and could use a huge amount of online storage/backup/file syncing.
For $100 a year, here's what your Office 365 license gets you:
- Full use of the installable versions of Word, PowerPoint, Excel, Outlook, Publisher, and Access, plus OneNote (although OneNote is now free for anyone to use, it integrates with the rest of Office 365).
- These installations work on ALL your devices: Windows PCs, Macintoshes, Android devices (phone/tablets/ChromeOS), iPhones, iPads. So in my case, I have Office installed on my Windows desktop, my laptop, my *other* desktop, my MacBook, my Android phone, my Android tablet, and my Chromebook. All for one license.
- One TB (!) of online storage (or backup) on Microsoft OneDrive for your documents, music, photos, or whatever, using a Dropbox-like syncing tool that works across devices if you like, so I can access all my files and photos across all my devices all the time from anywhere, or just use it as an off-site backup. Acronis charges about this much for 1TB of online storage just by itself. Carbonite is like $80 a year. iDrive is like $70 a year. If you were going to use an online backup tool for lots of stuff, then you might as well do Office 365 - it's like paying for the online storage you were looking for, and getting all the Office applications for free.
- Full access to the online versions of MS Office. So if I'm at someone else's PC or at a business center in a hotel, or using the PWA version on my Chromebook, or need to do some office work on my Linux box, I can open up (a semi-reduced feature version of) Word or Excel in a web browser, and if I'm using OneDrive (and I am), I can access all my files from that browser too.
- And then I can have 5 family members do all this too, all on the same license, because that $100 a year is for the whole family! So my wife each gets all these apps on all her devices, and she gets 1TB of device-syncing OneDrive storage too. So does my kid. So does my Mom. So does my Father in Law. So each person is getting all this stuff, including 1TB of online storage EACH, for about $20 a year.
Now don't get me wrong, I've used and recommended LibreOffice for years too, and I fully respect its capabilities, but Microsoft's pricing model for Office reminds me of Netflix vs. Torrents for movies: yes, Torrents are free, but Netflix is so much quality content for so little money, if you can swing a few bucks a month, it's worth it. So is Office 365.
Yes, yes, Hail Corporate.
(Ninja 2024 edit: now you also get a lot of extra online content and apps for your license too. Other than product names, everything I wrote 3 years ago still applies. If you have 6 friends who need Office and a TB of online storage, each of you chip in $18 a year and stop worrying about licenses.)
