I see this forum as a regular social media where you can express yourself more on a cryptocurrency issue. So phone will do just fine, with your mobile phone you can walk anywhere and still have access to forum, buy you cannot do that with a PC. It's very insecure to use PC outside your residence as that could attract burglar to your residence. On contrary, PC could make your work look fast and neat as you have a wide and clear view unlike phones where you'll have to zoom too close before you'll be able to identify each character.
