I can't honestly figure out why people would want HD support on the N900..

The ONLY time you'd be able to take advantage of it would be in some sort of streaming situation where you were streaming HD content from the device to a display that could support it.. but wait.. you can - in effect - already do that, so honestly, what's the deal?

As has been said many times over, the display on the N900 can't show you HD content, nor can the TV-out cable, so WHY would you want to bother with having the CPU/GPU work overtime downscaling it on the fly? I think you'd probably get better picture quality using a dedicated app like Handbrake to do your downscaling than having it done on the fly. You'd certainly get longer battery life.

Is it just for the convenience of not having to re-encode your HD content before you can watch it on the N900? I just don't see any other reason..
