I'd have to agree with JB on this one. I've got LOTS of code that's very dependant on that "filtered view" comming back instantly. Just try using a TOP n in a SELECT statement and see the difference in how long it takes to execute on a table with a 50K or more records. Please, there are uses for the beast, don't tame it!
