I am wondering what the difference is between all of the different devices (Slingbox 500, M2, M1 or 350). The price seems to have a large range but from what I see on the website the only thing is its ability to connect with youtube?
The only real difference is that the 500 has an HDMI IN/OUT. The M1 was a replacement for the 350 and the M2 is identical to the M1. Because almost every TV provider has now implemented HDCP Sling decided it wasn't worth fitting an HDMI socket in the M1/M2.
