I always play on the computer. Only if I have problems with the main Internet, I switch to play on a smartphone. It doesn't matter which instrument to play. Well, except that the screen size is different.
I used laptop several years but not anymore ...There some disadvantages on mobile users like most of poker rooms haven't got mobile App or the app has limited games on it .I play pokerstars and has them all except home game .Well that's limitation because of my country and not because mobile app
I enjoy playing on a PC, a laptop to be exact. I can move around the house or on my outside deck. The screen is bigger so I can multi game and multi task (like reading or posting on CC forums).
It depends on the needs of the person who will use them...
Personally, I haven't used a mobile device in years; i have played through it and i find it quite mobile… I'm on a laptop now, but if I had to choose between the two, I'd choose both, they complement each other wonderfully.
I play by PC,but sometimes by tablet.Playing by mobile phone is suffering because of the small screen.Tablet is much better.But the most experience of course the PC.
I play on PC. I have a terrible smartphone on which it is very uncomfortable to play. That's why I have to win our monthly freeroll on PokerStars and buy myself a new smartphone soon
I prefer to play from both but mostly I play from my laptop because it's easy for me and I play from my mobile phone when I am doing other tasks aswell.
I always use a PC to be able to open several windows, but also the applications on my cell phone in case the power goes out. In those cases, I continue from my cell phone.
