Exactly...so it's like your iTouch, but with a larger screen. It allows you to do things you wish you could do on your iTouch but can't because of the screen size limitations.
I already mentioned that it has a bigger screen and a better processor but how is the OS different? From what I've seen, its pretty similar. Yes some of the applications are better of course, since they have more screen size to work with, but the OS itself looks pretty much the same.
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.

Nicely said wot_fan, good comparison.
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.
To the user, does the core different really matter? If they look the same and function much in the same way, I would say it's the same.
And yes...Snow Leopard and Leopard are basically the same OS in my eyes. Different OS's would be like OS9 and OSX...now those are different. Or Windows 7 and Windows XP.
Sayings Leopard vs Snow Leopard are different OS's is like saying iPhone OS 3.0 is a different OS than iPhone OS 3.1. It's just a different revision but still the same OS on the user front.

If this is like the Sprint Overdrive, the 4G usage is unlimited, but if you fall to 3G you are limited to 5GB a month and have to pay 5 cents a MB for all additional usage. With limited use at home, I use easily 6 to 7 GB a month, in a 3G or Edge service area. So, unless they change their service plan, AT&T would still be a better deal for me.
