Like a lot of folks, I'm sure, I am frustrated with a single subdirectories limitation for the Photos app. I ended up buying Photo-Sort to fix the problem and although it only costs $1.99 it just seems that Apple did this deliberately to generate extra revenue through their cut of sales of Photo-Sort. Now I know that we have all gone from iOS 4 to 4.3 for free, whereas from XP to Windows 7 costs a good $100. So, what say you, fair or unfair on Apple holding some functions back? And please let's not do the Flash thing. It's been done to death.
