So you are telling me a smartphone is only smart if it does stuff AFTER installing a bunch of apps?
Tweeckdeck doesn't do LinkedIn.
Errrr, well, if you do things besides access social media and webpages, yes.
There are better ways of presenting information than another browser tab. Some apps measure height, width, distances, gps coordinates, triangulate locations, pin waypoints, photowaypoints, reencode audio, video, trim and edit audio or video, add video transitions, estimate square footages, cubic yardage, convert from one standard to another, apply vr filters to landscapes, sync photos, sync files, tons of things.
A smart phone is not, should not, be limited to only browsing and accessing the web. Offline tasks are tha shizzle for improving and helping in everyday life.
