You will need a third-party add-on to connect to a projector/vga/tv.
Margi has one that will connect to projector/vga, not to a tv. It will work with the X3 series but not the X5's.
Lifeview has a CF that works with projector/vga/tv. Of course, it works in the X5's but not the X3's.
Given the two IO slots, if the PP is the important part of using the Dell, which pda you get him may decide on which PP presenter you want/need to get.
