Same version as my mobile phone. (After the latest update)

I played around with it in the past, not recently though.

MAC-based access control lists are simple and lightweight. Which is why I use 
them for WIFI networks (apart from the guest-WIFI). But I don't consider them 
secure enough to only rely on those.

I only actively set MAC-addresses for VMs to avoid duplications. I don't see 
the point in setting them specifically as they tend to be unique in my 
experience.

Only other reason I can think off for changing the MAC-address is to get around 
a MAC-based filtering.
