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.
In my case, I tend to access the casino using my mobile phone rather than using my PC. We all seem to deal with mobile phones more than PCs and mobile phones have accompanied us everywhere making it easier to access anything including casinos. It does tend to come down to individual preference, and so far as comfort I've tended to use my phone to access the casino.
In the end it's up to us which one we are comfortable with, it's always no one else's problem. After all, mobile phones are safer to use to access casinos anywhere than PCs, especially in countries where gambling is not legal.
