Faster, cheaper -- and much more accurate. Slide rules gave answers accurate to two decimal places; even the cheapest scientific calculators give answers accurate to eight or more places.

Wow, sure glad I didn't throw out the ones I had from college days (etc.).
Who ever would have thought that they'd eventually be worth ~10x their
original price, especially when they were replaced by electronics that were
faster and cheaper?
