I am starting to use these applications for professional presentations, usually not to recover a poorly shot image (most stock images are of excellent quality), but to harmonize images across a presentation with a certain look and feel that is consistent.
Photoshop is still great for removing backgrounds from images, and inserting a 2D image onto a 3D surface. However, its artistic filters are far too dramatic. And making quality adjustments is tricky. It requires a lot of skill to darken a background, lighten a foreground or vice versa. You had to familiarize yourself with alpha channels and the fundamental ways digital images are stored.

Initially I bought the iPad app, which made me purchase the Mac app as well.
Still, I need to rely on Photoshop to control the exact dimensions and DPIs of images. Software innovation by small independent companies comes at the price of a more complicated workflow.
