I'll jump in to the fray, for a moment or two. Holgas are just another tool, another way of taking photos, that removes the technology, the fiddling of knobs, the search for the "perfect" image, removes the "I-have-the-latest-greatest-Moneyflex3000-with-State-of-the-Art-Art-of-the-State" cache that is frequently attached to more mainstream hardware.
I have Hasselblads, and a Mamiya 7II, a Yashica-Mat or two. I have a Nikon F3HP, and an F100. i have Leicas. I have a D700. And about 15 Holgas. And 10 original Dianas. And a Lubitel converted to a Zone Plate. And pinhole cameras made of matchboxes. And a bunch of other toys. They are all tools. Or toys.
But if I just want to go out and embrace the genuine pleasure of exploring with a camera, I derive as much joy from using my Holgas as I do my Mamiya 7II.
I love Holgas, I teach Holga workshops, I have even curated an exhibit of Holga images, which you can check out here:

If you want to check out some of my Holga shots, you can see them on Flickr here:

Bottom line - some folks like 'em, some folks don't. Many of my friends believe me to be a lunatic, which I have no interest in disavowing.
I like 'em, always will.
But I love my Mamiya 7II as well.
Must be nuts...
