The 7.2 inch 1280x768 LCD kit+HDMI+ION platform PC +laptop slim BD drive = much better portable BD player
You could even rip the BD to a 500 GB hard drive and install that instead.
Getting back on topic though, I may install a blu ray player in my 7.2 inch projector. If I do I'll post about it.
The Dark Knight still looks very very nice in 720p on my sharp kit that I just got.
