Are you looking to get into it because you want a good keyboard that feels good; or do you want to get into it because you like the idea of weird layouts, building your own keyboard, trying different switches, weird color schemes, custom key shapes, or all the other interesting but not typing things you can do. Nothing wrong with that second group, even though you can probably tell from my tone that I don’t see the point myself (if this is you I can’t give good advice so stop reading).
I’m surprised arbitration holds up. I can believe the court say it comes first and the reasoning of arbitration should be given to the jury along with instructions that they can disbar a lawyer who tries to reverse something the arbitration decides when arbitration was correct, but ultimately the right to a jury trial is required.
