Having demos is a two-edged sword, at least for the developer. There are plenty of XBLA games that I bought because the demo impressed me, but probably equally many that I wanted to play, but was turned off by the demo.
Overall though I think it is good for the platform since devs will have to spend more time on QA, knowing people will be able to try before they buy. Of course that's only if they become mandatory for all releases.
