I remember using Skype when it was still in beta in 2003. It was simple, uncluttered, and it was only for audio. My friends and I were blown away by how clear someone sounded. It was better than a telephone and it felt like the caller was in the same room with you.
Finally, I can talk about OpenEmu! A long time ago, it wasn’t easy to find a way to play retro games (Nintendo, Super Nintendo, Sega Genesis) on Mac computers. It was always possible using Windows, but the software was ugly and not smooth to use. For Mac gamers, everything has changed since the release of a retro game emulator called “OpenEmu“, exclusively for the Mac.
