Use Google Goggles From Desktop

I think Google Goggles only runs on Android 1.6+ phones

So either you would have to run a Dev-emulator on your desktop or at the moment it is simply not possible. And since it's 1.6+ only, you won't be seeing a lot of the current HTC phones running it, which might slow down general adoption.

I have created a desktop version called Desktop Reverse Image Search,
which can make image search on desktop possible.
