The Free Software Foundation encourages selling free software. As the Foundation has written, "distributing free software is an opportunity to raise funds for development. Don't waste it!". For example, the FSF's own recommended license (the GNU GPL) states that "[you] may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee."
With mobile apps and a Google Chrome browser extension—and that's it—Chrome Remote Desktop more than rivals even TeamViewer for providing plenty of remote access between systems (you can't use it to control a smartphone or tablet, however, only PCs). You can connect to all your computers and devices that are on the same Google account, or get a code from others for a true remote session. You don't even have to have the browser running to get access to the PC. What's lacking is file transfer between systems, but you can get around that using Google Drive.
If you want to use Microsoft Office on Windows and Mac desktops, it'll still cost you at least $69.99 a year for Office 365 Personal—and it's probably worth it for the power those programs wield. But it's not 100 percent necessary: the Web versions of Word, Outlook, OneNote, PowerPoint, Excel, Sway, and others all live for free at Office.com. You'll have to sign up for a Microsoft account to store files online using OneDrive (5GB are free). But there's no lack of free options if you can live without the full-test versions of Word, Excel, and PowerPoint.
Practically the de facto reader for ebooks these days, the Kindle brand is more than just hardware—it extends to these apps and programs for reading ebooks (which you have to buy from Amazon, of course). Start the book on any device, continue it elsewhere—the Kindle WhisperSync feature knows where you stopped reading. X-Ray gives you insight into the book; GoodReads integration gives you a social aspect. The new PageFlip lets you keep your page while scouring the rest of the book.
At first glance, appear.in looks a lot like GoToMeeting. That's because both of them use the fledgling open-source standard called WebRTC (real time communication) to set up and connect users for video conferencing in modern browsers (Chrome, Firefox, and Opera, specifically). There are a whole slew of companies trying it, with names like Talky, imo, and Gruveo—there's even a Web RTC feature built into the Firefox browser. Appear.in outdoes them all. It has mobile apps, allows up to eight conference attendees, screen sharing, claims on customizable "rooms," and even just simple chat tools. You can even stick an appear.in room on your website.
