Here is a couple of recent papers on transposome-mediated construction of sequencing libraries:
Transposase mediated construction of RNA-seq libraries
Preparation of high-quality next-generation sequencing libraries from picogram quantities of target DNA
Transposase-based methods are much more efficient than the traditional fragmentation/end-repair/tailing/ligation approach. With fewer enzymatic and purification steps, template losses are greatly reduced and small-volume handling is easier, allowing you to use a lot less template. I think there is already at least one transposome-based kit for making sequencing libraries, and I am sure more are coming in the near future.
