I polled my family and found only my dad still uses a desktop. The rest have switched to tablets and phones exclusively. This is shocking because I can’t imagine not using a real computer 🙂 If personal desktop usage is way down, and businesses haven’t upgraded to Edge yet, could that explain the low numbers?
Edit: Guess that’s not the reason since Edge only represents 12% of browser usage on Windows 10. Looks like they released Edge before adding many of its planned features, so Chrome and Firefox are more attractive for now.
