Downloaded it and gave it a try and sorry Adobe, but this is far from good.
The Mac app is quite easy to use, but that's pretty much since it has no features almost.
Yes, you can do some filters and editing on the pictures, but you can't arrange them in anyway, Carousel only sorts it by date, and that's it. You can't group them and give them a name, like Vacation.
And while 59 bucks per year for unlimited storage is ok, 99 is not, considering that this offers less than the combo of iPhoto and Flickr, and costing twice as much.
No, back to the drawing board Adobe. It's a shame, this could have been a good solution, it's just really bad at the moment.
