* Fix the image degradation that occurs when exporting a jpeg to the camera roll. Currently, I have to email myself a jpeg and then download and save that on my tablet in order to avoid the incredibly horrible artifacts, noise and pixelation that your export algorithm is creating. This is beyond terrible and not what I expect from an Adobe product. Did anyone test this before you shipped?
* Include the ability to connect to Google+. Facebook is two years ago. Lead, follow or get out of the way applies here. If you were aware of how many photographers and digital artists are on G+ right now, you might jump on this one more quickly in order to capture that market segment before your competition figures it out.
* Include connectivity to other cloud storage platforms. Yes, I know you want to funnel users into Creative Cloud. You can't keep everyone on the reservation, though, and I bet quite a few potential customers will balk at the lack of support for Dropbox or Box.net or even Google Documents. You need to embrace the collaborative model and play nicely with other providers. Make yourself the 'missing piece of the puzzle' and they'll beat a path to your door. I have an (Android) office-suite app that I paid nothing for (seriously) that allows me to store documents wherever I please. This is what I need, it's what others want, you cannot avoid it, but you can limit your market penetration by failing to understand it. If I were in charge of this platform/product, I'd adopt the "I don't care where they store their .psdx files, as long as what they're storing is .psdx files!" Get it?
I have committed to doing a "365 Project" (one picture per day) using nothing but a Canon S95 and doing post-processing exclusively in Photoshop Touch on a Samsung Galaxy Tab 10.1. So far, I'm frustrated by some of the things that are lacking in Photoshop Touch, but I see a great deal of potential here. If you want an unbiased, in-the-trenches opinion of the product, or even just someone to help beta test patches, dot releases or updates "in the wild", drop me an email. I don't claim to be great, nor professional, but your software will be getting used on a daily basis.
