Aj_BlaZ wrotelol battikh point of view for using video calls well i disagree , video calls are important for many many things maybe your doing a presentation in your class and you want your friend ,family to watch it what would you do use skype ? i dont think so
if i want my family to watch the presentation, either i invite them to it, or i film it and then show them the movie, coz on a cellphone screen, they'll just wont see much... and phones not having zooms, the guy filming my presentation will have lots of fun, and people actually watching the presentation will enjoy having a guy standing in their view holding a cellphone...
and yeah, i'd use skype. between having a guy pointing a phone 10cm away from me and blocking the view for everyone, and simply having a laptop and webcam with better resolution, yeah, i'd go for skype.
