This all ties into Adobes CS6 Creative Cloud concept. So you can use open a document you created in an Adobe product to the cloud (a web-based server) and then download the document and manipulate it on a mobile device.
What's interesting but not surprising is Adobe is making the Android apps available first.
I have installed a few on my iPad and they are very basic but I suspect this will change rapidly.
The Creative Cloud concept is interesting too. Adobe appears to be adopting the metaphor of iPad and Android apps. You pay a montly fee ranging from $25 USD to $50 USD a month and you can download, install, and use any or all programs from CS6.
