I recently switched from iPhoto to Aperture to manage images on my computer. The experience has been mixed. I am really not happy with the performance. I'm hoping that will get better. Another annoyance it the fact that importing images from my iPhone does not prompt me to delete those images off the phone like it does for my camera. It turns out there is a simple fix for that but its not in Aperture at all.

Open up Image Capture from your Applications folder while your iPhone is connected. Click on your iPhone's icon under "DEVICES". Then choose the option "Delete after import" from the bottom left-hand corner. You can perform your import using Image Capture and send it to Aperture. This creates a project called "Image Capture" in Aperture. Of course this is not as elegant as what iPhoto does.

It turns out the Image Capture is a very useful tool. You can browse your images and see their EXIF data including GPS coordinates in a simple table view. You can import your images and delete them right from the simple interface.
