I'm on Windows.

A couple years ago when I switched from Outlook to Gmail (Google Apps), Google provided this awesome little standalone gmail client that was just a single-purpose Chrome install. It launched like a normal application, stayed updated when I updated Chrome. It was Chrome in a separate application that launched only gmail, stayed logged in really well, and "felt" like a gmail mail client, with the gmail interface. It had it's own little red envelope icon, it was a windows app. (I remember there was no Mac equivalent.)

I found it while looking through the "this is how you get your company to switch to gmail" documentation that Google provided.

I just repaved my box and now I'm looking for this thing again, and I had no idea it would be impossible to find. I've spent literally 2 hours looking, searching, googling, etc. I'm losing my mind.

Anyone know how I can get my hands on this? I used it all day every day for 2 years, so I know it exists :), but I can not find it. Any assistance would be gratefully received.
