Eric wants to play with Linux, but he doesn't want to write over his existing OS. He wants to write an ISO of Linux on a USB stick and then boot to it. Leo says that the installer for Linux should do that. Other options include Rufus.akeo.ie. Unetbootin is another. Leo does that with a wide variety of OS's on USB keys.
Amazon announced Fire TV this week, a device that is positioned to compete with AppleTV and Roku. Leo says it pretty much does the same things, but for an extra $40, you can get a wireless game controller to play games on it. Leo says it's essentially a computer running an Android OS; a smartphone minus the screen. It runs a quad core Snapdragon processor with 2GB of RAM, and will play Android games. Apple and Roku plan to implement this as well, but Amazon beat them to the punch.
