This is for version 1.1.1
Still needs a lot of work, I don't see much improvement over the previous version. Phase One claims that it runs faster which I don't is the case. I ran this version against Expression Media 2 on my Mac Pro and honestly I could not tell the difference! The only thing I noticed it got fixed is now shutter speed and aperture is showing correctly. I am still not happy the way this application opens high resolution images, when I double click on the image it takes 2 seconds or more to render completely!! Media Pro opens the image pixelated and after 2 seconds or more image becomes clear. Very annoying. For the stability I cannot comment but it did not crash on me while it was loaded on my computer. Lastly still missing three features on the image editor. I can see that Phase One is working on this application but their progress is very slow and I am not sure if I am willing to spend more money on version 2.

I am kind of pissed to pay another $59 for Media Pro 1 to upgrade from Expression Media 2. It seems after Microsoft messed up the iView Media Pro, Phase One took over to fix the mess!! I don't see much of the improvement except some cosmetic changes and a bit of improved speed and yes they added the original logo of iView in to the icon of Media Pro 1!! When you double click on the thumbnail to make it bigger, software does some strange in & out focus moves till finally image opens up. On the image editor part they have removed three items, 1) Brightness & Contrast,2) Preset Enhancement, 3) the one I liked the most Auto Enhancement. I don't know why they remove them and still charge more for a lesser software!! Bad move from Phase One:(
So bottom line is with this new release you get a iView Media Pro version of Phase One with less capability and more money out of your pocket. I was fool to pay $59:(
For the stability and runing the application I have not encountered any problem yet!
