you need to think of the projector/screen as a system. you can't watch anything without both. your wall, is the screen, but a wall has a very limited number of options. it's entirely possible that a painted wall will work for you, but it should be chosen that way, not settled on because of ease or price.
screens can make the image brighter, or blacks darker. they can spread the light out evenly to get a great viewing angle, or focus it tight to avoid light reflecting off the ceiling and walls. they can be acoustically transparent to let you put speakers behind them, or have a super fine weave so that the material is virtually invisible.
the main advantage to buying a screen is the number of options you have to choose from. you can get exactly what you need.
and all of that brings me back to my last post. I think you'd be better off painting a screen on your wall for now. then, after you're familiar with the performance, the 'wow' factor has worn off and you can honestly evaluate your needs, you can go screen shopping. by then you should know if you want a brighter image, or darker blacks, or both? do you want a smoother texture, wide viewing angles, etc. until you actually know what you want, it's a total shot in the dark. and good screens aren't cheap
