content: Great app. Adobe has been around for years and is still a reliable remarkably stable platform. Ive only had one problem that happened recently and not sure if that particular problem was hardware or software related. It had been with an older HP printer. I couldnt locate a driver with which to print a .pdf file. My own uncertainty is the only reason I give 4 stars instead of 5. Otherwise I love the fact this app is available and doesnt tie one to a desk top computer. Thanks Adobe
