What should I look for in a laptop with Core Ultra 7 266V: build quality, ports, and expandability?

  The 266V is soldered into mobile boards with no desktop version, so compare whole laptops: soldered memory capacity, SSD slots, USB4/Thunderbolt ports, display quality, and warranty.

  These machines sell on weight and battery life, but memory is fixed and ports are few; confirm the ports you need before buying or you will carry a dongle everywhere.
