I prefer desktop even for sport betting. I can search some information or to compare odds fast using PC. The phone not so comfortable for me. But when i`m moving anywhere - i have the phone with mobile apps and 1-2 casino`s websites. I can bet any moment, and it is very important for me - i prefer live betting.
A smartphone is without a doubt a very useful tool and it has become almost ever-present because of it in a short amount of time, but a desktop computer also has several advantages over it.
With one of the most obvious being able to switch between screens at a very fast speed and with little effort, something that is a must for sport bettors, as you want to compare all kind of stats and the odds of the several bets offered by casinos, so you can find the very best bets offered and wager some money this way.
I also can use 2-3 screens and the same time see the odds in 2-3 casinos online and watch the match. Also, big screen and mouse much accurate than smartphone with the finger. And the last moment - websites mostly give more odds at one screen and it is really faster. Mobile apps often has different problems because the main part of casinos first of all develop their desktop apps and website.
