They downgraded the bus speed because of heat issues. They, and probably a lot of users, felt like the early 83Mhz units were generating too much heat. However, it wasn't a step backward, because the first Wallstreet PowerBooks didn't have a backside cache. When the next generation came out, they came with either 512k or 1MB L2 cache with added quite a bit of speed. I've never used a WS I, but I have been told the the WS II is faster than the WS I even though the former has a slower bus, simply because of the L2 cache.
