We were in same situation almost.
our cilent was using bitmap indexes on a column which gets updated but not that much. and it was OK very fast.
In your case update insert,delete would be abit slower but when you are having that many records then it worth it.

then our clint changed their licence from EE to standard edition and since bitmap is only supported in EE, we had to remove them all. by useing hints and .. we got almost the same respond time. Tom
