I can't say whether or not we've got an app in development, I'll leave that to the product managers to address. (It's not a secrecy thing, I just don't know...) But a side note: for most of the functionality, you can use Ariba just fine with Safari. It's a little tough due to the iPhone's small screen, but it works pretty well on the iPad.
In fact, in my training class today, a student's computer was acting up and she switched to iPad. It's starting to become a bit more common. I agree that an app would be better, but don't discount the iPad as an Ariba tool right now.
We have been talking about what areas we should focus on for mobile applications. We need to prioritize what applications to do first, what customers expect etc. I would like to talk to you indepth about your needs and requests.
Please send me an email at firstname.lastname@example.org. Then we can setup a time to talk over the phone.
