If you really want a good experience, then go for 30" + screens. There is just no way a 24" can give a better experience than a 32" even with 1080p support. XBOX 360 supports wireless controllers, which means you can sit back and relax on your sitting arrangement more than 3 metres away. End of the day, it all depends upon the distance you are place urself to the screen. If it is 3 mtr+, then abandon the dell 24". This is my personal and practical experience with TV and consoles.
