Roger convinced me - What's the road forward?

Hi all. I didn't know about everything that had gone on with bitcoin and bitcoin cash until I watched a few Roger Ver videos. After hearing both sides of the argument, I have to side with Satoshi's original vision. Which in this timeline, means bitcoin cash. I do have a few questions though:

1. How powerful did the computers need to be in order for the smaller block-size guys to be happy? They wanted everyone and their dog to be able to run a node, but they couldn't because you couldn't do it on dial up and a potato PC. If you wanted larger blocks anyway. So what kind of computer did you have to have for larger block sizes?
2. What does the road forward look like for bitcoin cash? I think it's safe to say that after the split, we got reset back to 2009 or 2010. Bch had to start the long road forward to mass adoption just like bitcoin did. It will probably be a bit longer now. And love him or hate him, I think Richard Heart is right about something - They really should have cut the mount Gox trustee out of the aidrop for BCH. And a few others. Because all they'll ever do is dump on you. But one day they'll be out of money to dump at least.
3. Is there any video detailing how to get a merchant set up to take bitcoin cash as a payment?

Thank you!
