Building an ARM64 laptop

The usual PC vendors will be producing ARM64 Snapdragon based laptops within the next 9 months or so. Microsoft announced an initiative with them to produce laptops with ARM procs and LTE modems. Who knows what hoops you'll have to jump through to get another operating system onto them, but I can only imagine it will be a matter of hours after they go on sale that someone will have Linux running on them.
