Speaker volume of the Pre

The external speaker on the Pre is located in the top back, a good place for shirt-pocket listening. The strength however, is, while not weak, at the limit. I usually keep the volume control at 8 of 10. Sometimes, in anoisy environment, I have to turn it all the way up to 10. It seems like 5 of 10 would be more appropriate for normal listening. On the iPhone 3GS, by comparison, it's continuous slider delivers good volume at about 60%, leaving room to boom, so to say.
