These are very confusing to use and they absolutely will not catch on in the near future. Whole numbers are easy, even if they are big numbers. Even laymen know what 100,000 is, but good luck trying to get everyone to understand what 1/1000th of something is. People ARE familiar with 1 cent and 10 cents, though. Bits uses large whole numbers and familiar fractions to be perfectly convenient. A $300 computer for 672,000 bits is NOT confusing.
