In November 2005, Nokia released the N770 handheld tablet. And, shipping with it, was Maemo, a Debian- and GNOME-based Linux distribution focused entirely mobile devices using the Hildon Desktop environment. This was a full-featured Debian desktop right in the palm of your hand. Even now, this little beauty still brings a tear to my eye. Over the years, this system would be updated and fancied up quite a lot. Why Nokia opted to ditch this in favor of Windows Phone still causes me to scratch my head.
