I have only seen a few latptops with HD-DVD drives and none of them can burn a HD-DVD, they are only HD-DVD ROM drives. I have also never seen a Blu-Ray drive in a laptop yet so I don't think laptops are really gonna shift this battle. Also, what makes HD-DVD drives more compatible than a Blue-Ray drive? Most if not all Blu-Ray drives do regular dvds as well.
Toshiba and HP are starting to put HD drives in their lap tops. My new HP came with a HD drive and a HDMI port. And with the way computer technology is constantly changing I imagine within the next 6 weeks there will be a lot of lap tops out with HD DVD.
