I like read aloud text because it requires very little preparation. Without it my game sounds like this:
Me: "You go through the door, in the next room you see....umm....a bed in the east corner. There is also a secret door....uhh...nevermind, I'm not supposed to read that part. There's no secret door there. At any rate, there's table in the middle of the room. On it is a ring of regeneration and a...wait a second, I guess you guys don't know that is a ring of regeneration without identifying it. Umm, so you see a ring and a sword."
PC 1: "Alright, I pick up the sword and the ring."
PC 2: "I search the bed. Is anything hidden underneath it."
PC 3: "I start searching for secret doors!"
Me: (scanning the rest of the room description to make sure I didn't miss anything important) Umm, one second.
Me: (finally getting to the end of the room description) Also, there is a Troll in the room that attacks the first player to enter the room.
On the other hand, when I have boxed text, I can read it without having to read it in advance and censor myself. It had already picked out the most important parts of the room and put it in an easy to manage package.
