I would assume most gamblers use their laptop anyways.
In our country, most gamblers who play online are using smartphones, even squatters people are using smartphones or android mobile devices because this is all they can afford to use.
Then, online casinos are also very rampant in our country.
I think that laptops are rarely used so that they can play online gambling, in fact, because mostly the main target of gambling promoters are poor people
who often just rely on luck or easy money in gambling.
