I've thought about this thread for a bit, is this all about durability of RD 1 or is it really just RF vs SLR talk, so lets look at each?
The RF vs SLR part really is all about the way you work and your style of shooting.
Lots of pros and cons here,but like most I have found a way to work that suits me and has helped me develop a certain style.
It's RF based, predominantly becaause I like to see "outside" the frame and I rarely use anything longer than 50mm [in 35mm terms] I also dislike zooms, preferring to use 2 bodies with different focal lengths [28mm and 40mm for 35mm] and my feet.
I won't work from a bag, I use a small vest, more discreet, although being a "big guy" I think I am not really that invisible IMHO!
Prior to digital this boiled down to using two M bodies+5 lenses, and an xpan + three lenses for the pano/landscape part of what I do.
Enter RD 1 and I switched to 2 RD1 bodies with the same five lenses but using 21 and 28 as the normal pair. Still have the xpan etc. for the "other stuff"
ALL this kit plus a vivitar flash , a small slave flash,gels, cables , chargers x2, batteries [5 spare], cards [8 spare 2gig] gossen meter , filters for xpan travel in a Billingham Hadley, try that with 2 DSLR and similar kit!
So OK for convenience too..........
On to durability.
I now have three RD 1 bodies [ all bought here on RFF total cost less than 1 M8 when it appeared] , the most used with around 12k actuations, one at around 7k and one around 3k. All fine so far!
Most intensive trip this year :
3 days in Spain shooting Easter Proceesions, then cross to Morocco for 5 days to do another story on "timeless Morocco"
Total digital shoot Spain 1200 images,see:

use slideshow>full screen for best results
Total digital shoot Morocco 2500 images plus 8 rolls of velvia [xpan] and 3roll velvia 35mm full frame 12mm , lensbaby, fisheye etc. see:

use slideshow>full screen for best results
So around 4-500 RD1 images per day , yes, get through batteries, but always have two spare for each body ,charge 2 overnight and 2 during day. Still quicker than changing film!
Image quality speaks for itself , in the Morocco story there are both cropped and xpan panos, can you see the difference? [You can at A2 but how often is that used professionally]
So can you use RD1 professionally?
I'd say emphatically YES.
