I never assumed that it wasn't based on preferences, and situational preferences is a real thing as well, like lets say even if you preferred PC in general, when you are at work or at somewhere that you do not have access to your PC but have free time, mobile phone is the way to go.
I just wanted to point out that if you are capable of playing on your PC, like lets say you are at home and you have nothing to do and you can open up your PC and open up your phone, both are possible, there are STILL people who prefer the phone option. That is true, and I understand they do, I just do not understand why because it's visibly different and much bigger with details on PC, it's fine though, maybe it's just me and that's okay.
There was once a thread that discussed which device was the most preferred
https://bitcointalk.org/index.php?topic=5330179.0, PC, Laptop, Phone or Tablet but that thread was already two years ago with the most choices being PCs and in my opinion PCs and Laptops both provide wider visibility than tablets or Mobile Phone.
Maybe now the trend has changed so that more will choose to play with mobile phones, but laptops are my main choice because the big screen makes it more comfortable when playing.
