I’m not sure how I missed it, but regardless, this past week, I discovered it. I ordered an 
ActionTec ScreenBeam Mini2 for $60 and, within 60 seconds, was projecting wirelessly from my Windows 8.1 laptop. It was easier than Google’s Chromecast PLUS it shows EVERYTHING on your laptop screen (instead of just YouTube and NetFlix). All you have to do is have Windows 8.1 (or buy the add-on kit that adapts Windows 7 and 8.0) and a monitor that accepts an HDMI signal. In (literally) seconds, you’ll be projecting wirelessly. For maximum performance, you’ll want to be within 12 feet, but regardless, this is a HUGE step forward. Learn more at…

Anyone know of anything like this that works with Mac’s & iOS devices? I know there is the AppleTV but I’d like something smaller and cheaper. Thanks.
