Who says it's obsolete? You can only talk obsolete when you're in the realm of the digital camera because all that stuff gets better as computers often do, so today's wunderkind DSLR will be obsolete in a couple of years. As far as film cameras go, if it's still serviceable and fixable, like a musical instrument it will never be obsolete because you as the artist will make it play, and you'll have bigger negatives that will trounce any full-frame DSLR today. And you'll still have those negatives for decades that you'll always be able to scan.
I've been playing around with my just acquired Bronco SQ system and I am digging it. Compared to 35mm, the 6x6 negative is huge, and it's resolving power can only be surpassed by an even bigger negative (like 4x5). You should check out some MF work, there's a super high-resolution, creamy quality to the prints, it's addicting. My 35mm negatives look "amateur" next to MF.
Now whether or not I'm making a good photograph of something is another issue
