Few reasons that helped us decide to settle on this projector was, first the fact that it supports wifi and we can directly cast to the screen, and that seems to be working with no problem. Other factor is the high brightness that you should never compromise on when you invest in an expensive projector such as this one. It makes a huge difference how the environment lighting may effect your viewing if the brightness is not adequate, or else you always have to be in totally dark room to get a decent picture. The fact that this projector is like a closed system sounds like a great idea to make this suitable for frequent outside viewing, any way they can keep the dust away from reaching the electronics inside can only help make this unit last much longer without the loss of picture quality over time. Yesterday watching a game was really enjoyable on a 100" screen and when connected to a bluetooth sound system it felt like a theater like experience. Oh also glad there was no noticable heating issues either so all is good for now and we are enjoying it, but if any issues I'll be sure to report back here.
