I use Fedora (I like the OS releases every 6 months, for those that dont get CentOS for once every 5 year or so revision updates or Ubuntu, although I always preferred Fedora/Redhat/CentOS GUI to Ubuntu’s). And i use Gimp, Libre, Google Docs on daily basis. Gimp really nailed it!
The only problem ive ever ran into is sharing stuff, where people have Photoshop or MS Office and you try to open their files or they try to open yours, but that was years ago, compatibility improved greatly since then.
One huge flaw with Google Docs is their version of Excel does not have functionality to compare cells between tabs (sheets). I use that functionality a lot in MS Excel, wish Gdocs had it.
This is a pretty good list. I really like VirtualBox. I was just thinking about looking for a free video editor, so DaVinci is the perfect, timely recommendation. I tried LibreOffice several times back in the day, all the way back to the StarOffice days. But I could never get over the ugly UI. I know you said it had been updated, but if the screen shot was indicative, I’m still not convinced. I’d actually use Google Drive as a free replacement for Office if I needed one instead of LibreOffice.
I’ve used gimp, and hated every moment. I’d rather shell out $10/month for Photoshop and Lightroom than use that. And if money was really tight, Paint.NET is awesome.
I have been using OpenOffice for years (Mac OS), like once a week, and while it does what I need, I find that opening docx documents doesn’t work out as smoothly as it should, what with missing fonts and formatting settings going awry (I use English and Chinese all the time). Is Libre Office noticeably better than OpenOffice?
BTW, any good alternatives to Adobe Acrobat (not the free Adobe Reader), especially one that allows individual layer editing?
