Will files made on a Mac, say with Keynote, open in the iPad version of the Keynote app?

I don't know... but I have to think that would very stupid if they did not.

Yeah, it's not like it's MS or somethin'.

Inquiring minds want to know--before purchase

Yes, they will open up, but there are some compatibility issues from what I've been hearing. The iPad version isn't as full-featured.

I hope that gets resolved soon!

Don't take this to the bank since I haven't been following this that closely:

A) is it a compatibility issue wherein the iPad will not play a Mac created version of keynote file perfectly?

or is it

B) The iPad does not have all the bells and whistles to add or create a file as deep and cute as a mac derived keynote file?

I would be worried about A and not be concerned at all about B. Who wants to create a Keynote file on an iPad? MAybe resort or delete a slide but that's about it. I just want it to play it when I walk to the podium. I am aiming to do that a few times in September/October with an iPad. I'll certainly have the MBA close by as fallback.

I wouldn't want to do B at all--that's why I'm concerned about A. My guess is that some of the flashier transitions aren't available on the iPad.

Damn, it corrupts.

Well I guess I'll wait till version two before I buy.
