I like that it has an interface designed for use by non technical people - very intuitive! It is really easy in general usage but there are times when you need more power or options than what can be offered at first glance (ie colour correction).
The fact we cannot transfer our project files from other editing software makes me wonder if this may restrict its future development compared to competitors such as Adobe products which allow direct file transfers between different types of editors / platforms etc? Currently using only basic functionality so unable comment further until full release version available however working well now & good value for money considering price vs performance ratio! Editing long term projects - no problems found yet though one could always think about them!!
