"Comprehensive info, easy-to-use."
So easy to run, yet so customizable. Incredibly comprehensive report of both hardware and software components. Great to document a laptop in the event of its loss. Reports produced in text, pdf, even worksheet format.
Can't think of ANY.
On a personal level, I use WinAudit about once a year to document my home systems (a couple of desktops and laptops). The information would be great for insurance purposes in the event of a loss. At the office I use it to document our corporate systems as required by law.
