Not to mention that /u/s/i is not discoverable and as such something else to remember while /u <tab> /s <tab> (will expand to /usr/sbin /usr/share /usr/src so /sh <tab> is better) /i <tab> is. Tools which are not omni-present yet claim to save time by making the user remember tool-specific syntax are often not worth the effort of learning that syntax unless the savings in time or effort are substantial - in which case the tool would probably be more wide-spread to begin with.
