I'll completely admit, that back when I was on Windows, and even using Windows back when I was a kid on the school computer's, (We also used MAC's as well) I really enjoyed Microsoft Office. It was rare that those APPS suite's would bug out on us, usually we ran into printer related problems more then we did the software suites lol.
And for the record, those printer problems were usually due to, too many students printing to the same printer all at once, and the printer not having enough memory to handle the load, which is why we had to get two more printers for the computer lab, to spread the work load lol.
I didn't mind paying for software that really worked well though. Yes, Microsoft software is expensive, I won't deny that, but at least it worked well. And I used Microsoft Word more often then the other's. So, what do you do when you switch to Linux? Well, you do what Emperor was saying.
You do your research, you learn what APPS are available to you, as a replacement for Microsoft Office. There is Lebri-Office, there is WPS Office, there is Open Office, there is many of them. Ideally, your going to find the one that works best for you, and once you do that, then you pay for the full featured version.
This way you get all unlocked feature sets, to allow you to be the most productive possible, and to get developer support as well. I know being on Linux isn't easy, God knows I have run into my own troubles with Linux, and even Zorin OS itself.
But at the end of the day, I rather not be a slave to the Microsoft devil, to use me as their product to make money off of, and invade my everyday privacy. Linux gives the choice back to you, and Linux provides you freedom, and security.
Anyways, thats my two cents.
