Video: HTC Desire running Desire HD ROM

I'm not really into tinkering with the internals of my Android phone too much, as there's always a risk that it will get bricked and I do use it for stuff. Still, hats off to these folks (video below) who have ported the ROM from the Desire HD into the original Desire.. and now it boots up in just 3 seconds! Sure, not everything works.. but wouldn't it be nice if HTC (and other manufacturers) could do the same thing?
