Mobile phones are a lot easier for me based on the ease and convenience of carrying it around, because I do a lot of walking around and it might be stressful and risky for me to walk around carrying a laptop and bringing it out just to reply comments or make post here.
Also due to the fact that phones can be more discreet to use and more economically friendly as regards data consumption cost, I find it more easier and more enjoyable to use, unless I want to make an elaborate post or review then that's when a laptop or desktop would come in as number one option of choice.
Mobile phones are a lot easier for me as well and I don't think I can ever get use to using my laptop to browse through the forum, desktop are the worst if I must say, imagine sitting down in one position for hours working, I'd be restless and uncomfortable. Mobile phone makes it easy because it's always with me everywhere I go but there's a disadvantage and that is you can't make reviews, prepare a report table, upload images and add data with just a mobile phone so I guess I have to start getting use to using my laptop from now on.
