We all come here to share our experiences and knowledge in the use of these sophisticated cameras. I personally couldn't care less what anyone chooses or doesn't choose. I learn a lot here, and share a lot here, and do NOT find it to be an overly "sensitive" forum at all ... but will share knowledge or opinions if I disagree or have another perspective.
Based on experience:
Dust will eventually get on the sensor of any digital camera with a removable lens unless you only use it in a computer clean room or never remove the lens ... including the S2. People who shoot a fully weather sealed Canon 1 series pro camera also have to clean the sensor from time to time. The weather sealing of the S2 has other major advantages for certain types of shooting, but a spotless sensor isn't one of them.
The H battery is no different from any other Lithium battery. Reseting the battery fuel gauge is usually attributable to not conditioning the battery per instructions in the manual ... which people tend to not read, and then wonder why something doesn't work the way they want ... been there, done that myself
.
I noted the procedure to reset the H battery fuel gauge in my post above. It takes all of 5 seconds, and once done shouldn't be needed again ... IF you follow the directions in the manual and deplete the battery fully a couple of times a year and then fully recharge it for 12 hours. I rarely, if ever, need my second H battery during a shoot.
Plus, we have to remember that the H camera uses one battery to drive both the camera and the back as opposed to the need for two separate battery supplies on other MFD modular cameras.
If you do long sessions in the studio with the camera on for long periods of time using lots of the energy draining features, I recommend the AC H power grip. I also like it because I always have a powered camera for impromptu shoots without having to worry if I have a fully charged-up battery at the ready all of the time.
If you repeatedly have to re-set anything else on the camera, then something is wrong and your Hasselblad dealer should be consulted.
That's the info based on actually using this stuff for a long time, take it or leave it.
