The HDMI input is a welcome addition to a projector in this price range. With more computers and video sources using HDMI, it makes for an easy connection that can deliver audio as well as video. Also welcome is the ability to adjust the projector height in both the front and the back, thus reducing the need to use keystone correction.
As far as negatives are concerned, lamp replacement will not be easy if the projector is ceiling mounted. The on-projector controls are difficult to see and use, but most people will be using the remote anyway. On the plus side, there are no dust filters to clean or replace.
