SpeedCrunch has a Windows Portable Edition (as in "carry-with-you" or "no-installation-needed") since version 0.10. The lastest release, 0.10.1 (May 24), has a Portable Edition download count of almost 11000 as I write this (source).
But since August 22, our fellow folks at PortableApps.com have incorporated SpeedCrunch in their distribution (page). This is absolute good business for us, since the download count is at this moment a bit above 47000 (source).
This is quite impressive and gives SpeedCrunch yet another boost, since it basically doubles our Windows (installable and portable together) download rates for 0.10.1. A big thank you to portableapps.com!
