Form or function?
What would interest me is a description of what new things I will be able to do with Mint / Debian / Ubuntu / any other new linux distro, that I was unable to do before. What "killer" apps it now contains, that weren't there before? What functions that previously were difficult or convoluted have been made easier? What giant strides have been made in the documentation (OK, that one's a joke).
I am sure it is nice to know that the colour scheme has been diddled with - that we can now have yellow folders. But if that makes it to the list of newsworthy features, I feel there isn't anything more significant that would entice me to upgrade.
