more water injection

[Dirk Wright]

OK, here's a really dumb (but interesting to me) question: If water 
injection is so great, why is water in the gas considered so bad? Why 
bother with products like "dry gas" if water in the cylinders is a good 
thing? Why do most engines run so bad (I think) when there's water mixed 
in with the gas in the tank? 

I can understand the freezing bit in winter, which could be cured with 
added alcohol of glycol, but if water injection is so good, it seems that 
you could save yourself a bunch of hassle by just adding water to the gas 
in the gas tank. Is it possible that you only want water injection under 
certain circumstances, like WOT? If so, then I could understand the need 
for dry gas and a separate water injection system. Otherwise, what's the 
deal?
