Playing around with Aperture 3 I come to the conclusion that it just doesn't make the cut when it comes to speed, usefulness and IQ, to be in my photo editing process:

I have this sensation that Aperture (although a very good software) isn't a product for photographers, but it has been developed to the computer geek that occasionally takes pictures.

It is very slow and after closing the program, my machine seems like it went to an halt.

After using to process 1GB of files I've decided that I'll stick to my line of editing... LR+Photoshop. It's far more productive than all the bells and whistles of Aperture that don't even come close to what I already use. I'm passing this one...
