Consumers are either deciding on a format or waiting until a decisive winner is declared in the ongoing HD media battle. Most people think the battle is Sony vs Toshiba, but I beg to differ! The other half of the debate is Java versus Microsoft.
Now wouldn't it be lovely if HD-DVD used .Net for authoring content? Well of course, it's not that simple. From my brief research, both can allow you to use JScript, but Blu-Ray allows you to also use J2ME. Blu-Ray is by far the superior platform technologically. But as we all know, more complex will always lose out to easy and simple, where the consumer is concerned.
As of this weekend, I now have both formats thanks to a PS3 and Xbox 360 + HDDVD add-on. I'll be posting soon on how I came about doing this and why.
