I don't understand why they didn't switch to USB-C to power these laptops? I'll pass, my 2013 Lenovo Yoga 2 Pro is still going strong and since I don't play games on it, there is like 0 reason to upgrade which is kind of sad for laptop technology.
However, what's really annoying to me are laptop manufacturer's who switch completely to USB-C so they can save 0.001 mm of space or something. Every device I own to plug into a laptop is USB-A other than my cell phone, which I would never plug into a laptop anyway.. The best thing IMO is to have an USB-C power cable that can also be used to output video and then have a 2nd USB-A port for compatibility purposes to use with external hard drives, flash drives, mice/mice receivers that are all USB-A.
