It's irrelevant whether or not I have an example of better technology. Criticism of how iOS5 and Photostream works is legitimate. And while YOU might love it "as is" - others might not.
Further - if management tools were in place I am sure you wouldn't complain. Or would you?
I remember so many people were annoyed when myself and others suggested that the iPad would benefit from a camera - at least front facing. Oh the comments on how stupid of an idea that is because who's going to use the iPad as a camera and it's not the right form factor. Yet I see people GLOWING over the iPad 2 and the fact it has a camera.
Don't be against additional functionality - even if you won't use it. It's better to have the choice then none at all.
Nobody's against additional functionality. It will come - in time - just like Apple always does. Their first shot out of the gate never has all of the functionality that everyone wants. They dole it out year over year - partly to ensure that they have something robust and working before adding all the bells and whistles, partly to create demand for the newest thing. Just like the iPad 2 bests the iPad, the next iteration of Photostream will be improved. But no sense bashing the initial version and saying how poor or underperforming it is. For what it is, for a version 1.0, it's pretty darn awesome. Being "annoyed" at something because it doesn't have everything in its feature set (yet) that you or others think (i.e. "a botched launch") is a "must have" is trite.
The first iPhone didn't have a retina display. The first iPad didn't have a camera. The first iteration of Photostream doesn't allow you to delete. So what? Use it, enjoy it, and be happy when it gets added in a year. No sense hating something now because it's not perfect.

Google has offered a similar service for a while and there are many third parties that have been offering it on Android for years.
It's harder to do on iOS because Apps can't do tasks like this without being open, but there are some that will do it for you by simply going into an App to trigger the process.
I'm not familiar with an app that automatically syncs all of the photos I take on my cellphone with my tablet, my iMac, and my PC. I have apps that allow me to transfer images wirelessly back and forth between my devices, but I have to activate them. Which one(s) on Android can you point to, so my wife can put them on her Droid, Macbook Air and her work PC, so she can have the same experience that I have?
