It is similar, but it’s also different. I still think Apple wants to avoid mixed mouse and touch interfaces and also wants to avoid switching on the fly between those two interactions models on the same device. Their goal will be to give developers the tools to use a shared codebase, but still being able to provide the right accommodations for mouse input on the Mac. I don’t think touchscreen Macs are planned.

How well they can pull that off is a different question altogether.

Mac users feel neglected anyway, so I’m very willing to let them try.
