For me, the 5200 VCS adapter is very practical. My 2600 is in storage and haven't played it in years. I bought the new 2600+ joystick and when I want to play the 2600, I take out the 2600 adapter for my 5200 and hook up the 2600+ sticks. I save lots of space and I can quickly switch from the 5200 to 2600 without all the wire changes and needed space needed for 2 consoles.
