What hardware updates DS Lite got over original one?

And if you want to be that picky, PS2 actualy had quite a lot models rather than just original and slim, which differ slightly in hardware and firmware. That's would be a few dozens of PS2 models. So, please, define what changes in hardware and firmware are big enough to consider it a 'new' model.

When SW written for the new version can't run on the old one?

No, it seems that is not a valid definition. Just check some replies on this thread!
