I have a Diztronic right now and a Pop on the way. If you can wait until tomorrow or Saturday when it arrives I can post pics.
I think the Pop will be bigger.
FYI, the POP is being redesigned and will ship end of the month. The ones out there now don't have wide enough openings at the usb port and no opening for the second mic on the back.
The Diztronics have been replaced because the originals had volume button locations that didn't line up correctly.
Both cases are being replaced free of charge to customers, but the pics I will post will be of the intial cases, not the updated ones. The thickness won't change but it gives you an idea.
