alt Hacker NewsYeah, that's basically my point.
The only way it would make sense to use your phone is if the keyboard and monitor can fold up so small that they can attach to the phone and still fit in your pocket. Otherwise, just using a laptop is going to be better every time.
What you're asking, a laptop that can fold so small, requires materials science breakthroughs that we cannot bet on. A cheap slab of pure aluminium will be king by the time we're both dead. Mark my words.
