It really is... I'd agree it's a feature, if it's able to remember it's last intensity state. Then yes it is a feature. Now it just looks like a bug which they ain't willing to admit, so they call it a feature. Yet i'm pretty sure it's not that complicated to fix it. The way i see it, it (intensity state) could be either saved to internal memory chip, where the firmware resides (it's just a matter of a bit or two), or some very lightweight daemon / service could be started just right after the OS boots.
