I guess he's entitled to his own opinion. Linux isn't perfect but is getting better by the day. I personally prefer Xubuntu, which is based on Ubuntu but uses the xfce desktop environment and is a damned near perfect replacement (or companion) to Windows 7. In fact i have it installed on 3 laptops and 2 desktops.
I personally don't see the appeal of Debian. I like things to work out of the box instead of having to install this and that all the time. Rarely on Xubuntu have I run into a situation where something didn't work or wasn't installed by default. Its relatively light on resources (unlike Linux Mint), isn't weighed down by inane bells and whistles (like KDE), and the xfce desktop environment is lightweight and DEAD SIMPLE TO USE because it sticks to the traditional desktop metaphor instead of using stupid resource hogging shells like GNOME 3 or Unity.
I also abandoned Linux Mint because its software repo, well, sucked.
Windows > Xubuntu > Android > Any Apple product. Being totally honest. I tried to use an iPad once and just gave the f*** up. Locked down garbage.
