I know there are several photography people on the board, so I thought I'd mention Thumbnailer which I just started playing with this weekend. Better on a Tablet though, not something I'd run on my phone...
nef-Thumbnailer (and cr2-Thumbnailer) are let you view RAW image formats from Canon/Nikon cameras. I ran a quick test, shooting about 300 images (a little under 3GB) from a parking garage. Was able to view them directly on the camera using my Moto Xoom, with the ability to zoom in, share, save, etc. Having that extra screen size to review images is great, letting me delete a lot of images (shoot in continuous mode, or spray and pray) and save space. I also have about 40GB spare on my Xoom, so pulling off the camera is great for saving space on my flash cards as well.
