Summary: You can't go wrong when you buy a media streamer for $7 that's not just "for parts." Unfortunately, it won't work with our Windows 7 & 8 laptops, but it does work with my work laptop running XP. I may be able to use it for a presentation. I bought the Roku 3 on Amazon, too.
Summary: I first tried this product using a laptop with 802.11g. I was streaming video from various sites on the internet (watching movies) and then putting them in fullscreen mode. I experimented with photo and video mode. Video mode is lower resolution.
