Even mac folks have their Macbooks at least twice as long as their phones.
So i dont see this happening for any kind of professional use anytime soon. But who knows.
Disclaimer: My last phone (downgraded recently, because battery life > 4k screens) is more powerful than my Laptop.
Not anymore they're not. I haven't bought an upgradeable laptop since 2011.
Written from my Thinkpad :)
If you look at my 2011 Thinkpad however, it was shipped with 4GB of RAM and a 512 GB analog disc. Spending only like $200 extra it turned into a 512GB SSD + 16GB RAM + new battery beast which outperformed my 2014 MBP for nearly all of my development tasks.
So i guess it depends on how you look at products. I tend to buy things i know i wont have to replace anytime soon.
The people who will buy a phone dock are probably also the same people that value ultra-lightweight devices, so I don't think you're in the same bracket as them
I use a tablet now for my idle couch browsing.
So for us devs it would mostly be for non-work stuff. And then you have the problem that you'd have to carry around external hardware with you or find places that offer it for use.
I think Apple are the only company that can pull this off right now, everyone else is too fragmented to get the hardware/software integration right, and popular enough for mass adoption.
If they release it they could tigger a whole new era of computing. e.g. Imagine going to work without having to bring a laptop along.
