Photo Editing on Android

I couldn't find a recent thread on this topic, and a lot has changed in terms of apps for Android, so I'm hoping it's okay to start a new one.

I am an 'enthusiast' photographer. I only save in JPEG. I use Picasa or Faststone for quick editing of my photos. I use Photoshop Elements for more serious editing.

I have an Android smartphone, and there are a couple apps I use to help in photographing: DOF Calculator and Photo Tools.

There are also quite a few fun apps for taking pics and for light photo editing. I use: ActionSnap, HDR Camera, Night Camera, Paper Camera , Photo Enhance, PicSay Pro, Camera360, and Picasa Tool.

One of the nice things about a smartphone that has GPS is that I can use a GPS tracker (Open GPS Tracker, My Tracks, or one of the exercise apps like RunKeeper or Endomondo) and then match the timestamps with those of my pictures to geotag them. (Using Geosetter or digiKam. You can also manually geotag quite easily using Picasa. Another great option is to upload the GPS data and pics to Breadcrumbs [ http://www.gobreadcrumbs.com/] which will automatically put them on the map.)

I have a trip planned this summer, and I will need to do some photo editing, but I don't want to take along my notebook computer, SO I'm looking for a versatile Android photo editing app.

The main one I have found is Adobe Photoshop Touch for Android tablets. ($9.99 for the app, so reasonably cheap - http://www.adobe.com/products/photoshop-touch.html ) It looks great as an in-the-field or on-the-go editing app, and using touch is probably lots easier than my mouse for editing.

I found this excellent and thorough review of Photoshop Touch. The author confirms that it is suitably similar to PS so that you can get going fairly quickly.

I think I could live with PS Touch, even keeping in mind some limitations I see from that review and from the Adobe web site.

1) Unfortunately, Photoshop Touch can save in a PSDX format which requires PS CS5 to open. It will not open in PSElements.
2) It has further limitations in flattening any PSD file you open in it.

3) It is only able to handle 1600x1600 resolution. (It will auto-resize any photo you work on.) PS Touch, therefore, looks to be a fine app for working on an Android tablet, but it is not a solution for working back/forth between the tablet and a full-featured desktop program. SO...

Does anyone have experience with photo editing apps for Android beyond PS Touch and the rather lightweight ones I mention above?

Thanks for any suggestions.
