Windows/Mac/Linux: TeamViewer, the remote desktop tool that makes for easy tech support or desktop viewing across systems, has released a Linux client, making it really helpful tool for Linux fans looking to provide a little cross-OS support for their friends.
Not that we're assuming that a desktop Linux user is the one always giving out tech support, but—okay, we kind of are. TeamViewer, one of our Hive Five contestants for remote desktop tools, makes helping out with computer fixes easier than setting up a VNC client on the ailing system and connecting. Reader PowerPatrick PowerPatrick pointed out the availability of the full Linux client, which is free for home and non-commercial use.
