2k? That's quite a loss.
For me, it's my smart phone always. For a number of times, I can count the number of times I used my laptop to gamble. Very few times.
When I use laptop to gamble, I easily get carried away and that's because I can easily switch to working mode. With my phone, it is portable and limit my time kn gambling site.
I cant really afford to play gambling while im in work because it is way too distractive for me and might result on less efficiency when it comes to your job.
If you can handle it well then i dont see any problems with that since we do have different preference.
