Let's be honest. The iPad IS a laptop replacement for MOST people MOST of the time.
We aren't talking about Enterprise where you're using Access, Excel, and SQL all day. Most people sit on their computers and use them for:
Internet
Snapchat
Banking
Reading
iPad checks all of those and does some of them better because they were built on mobile.
This seemed like an inevitable to me. Most people bought a computer in the last 20 years mostly because they wanted internet access. But they didn’t really want a computer, just the internet. In an abstract way it’s like how if you wanted a portrait of your family. You’d either have to paint it yourself or hire an artist. Then photography became a thing, became cheap and accessible and the painted portrait remains on the fringes.
