IMHO, the iPad is to the iPod Touch what a Laptop is to a Netbook. A laptop is just a better/bigger netbook. Even though they can be used for the same types of things, many those uses are less than ideal on the netbook. The laptop provides a much better user experience and allows the user to do things that the netbook doesn't have the horse power or screen size to handle. I believe the same is true for the iPad when comparing it to the iPod Touch.
Rumor has it, and I believe it, when iPhone OS 4.0 comes out the iPhone, iPod Touch and the iPad will all use it. Steve said during the keynote that devs could make universal apps that would run on both the iPhone/iPod and the iPad. IOW, the app would contain an iPad interface and an iPhone/iPod interface in the same binary. This seems to support that all the devices will be running the same OS.
It isn't the same OS tho...it is based on the same framework, but it is not identical. The iPhone OS is optimized for the iPhone and the iPad OS is optimized for the iPad...it's like saying Leopard and Snow Leopard are the exact same OS because Snow Leopard can run Leopard apps and they look similar. At it's core Snow Leopard is extremely different. But it is backwards compatible. Of course there are applications that work on Snow Leopard that don't work on Leopard.
The big difference here is that the iPhone OS and the iPad OS are being improved in tandem.....I'm guessing the updates will come out same day...tho they could be offset a bit.
The idea tho that the iPad uses the exact same OS just makes no sense...the OS core would have to be different to accommodate the newer and very different hardware. While apple is very good at making those differences transparent they are there.
