A few months ago I mentioned how I was using the digital camera to make copies of a lot of material for my dissertation. On the laptop, iPhoto is all that you would expect from Apple. Easy to use, doesn't hog memory, perhaps lacks some advanced features, can't quibble with the price. But I also manage some of my gigabytes of digital data on the PC at work, and frankly the default picture viewers in Windows weren't great. Enter Picasa. From Google. Highly recommended, and I am not on commission.
