Definitely. I remember at the time Adobe Air was still recently new and there was some buzz around in the tech scenes because everyone like Balsamiq Mockups, which originally was only in available in Adobe Air.

Then Apple announced they weren't going to support flash and overnight everyone realized flash was dead, and Air and Silverlight were both a dead end.

I was working on a Silverlight product at the time and it got canned soon after too, with Microsoft soon losing enthusiasm for it too.
