Moment of Inspiration 3.0 is a Pen & tablet friendly user interface.
MoI features a unique user interface that integrates particularly well with a pen tablet. Unlike most programs, you don't have to constantly tap the Shift, Alt, or Control keys, so you don't have to hover over the keyboard when using MoI. Also right-clicking tends to be awkward with a pen. MoI provides simple left-click methods for view manipulation functions that require right-clicking in other CAD programs.
High quality display on inexpensive cards. MoI displays gorgeous anti-aliased curves even on low-end "gaming" video cards.
