That's the perfect way to do it. If it's docked, you likely don't care as much about the charging speed. And if you're using on your lap or coffee table, you probably care more about the MagSafe aspect.
I've sworn off the past 5ish years of Apple laptops, but if they bring MagSafe back, ideally along with a non-Touchbar option, that just might be enough to bring me back!
Apple and Microsoft's Surface had (does the Surface still have?) the perfect connector - the Magsafe. The more we dig into this power over USB-C garbage, the farther away we go from that perfection. The patent expiration cannot come soon enough, I seriously hope all portable device vendors bring it back.
I don't believe this press release indicates which ports the laptop has. I assumed that meant it had a crappy selection, and further googling proves correct - 4 Thunderbolts and a headphone jack.
In my eyes, that makes it a non-starter for an alleged "Pro" laptop. For the professional work I do, an SD card reader (for photos and video), HDMI/DisplayPort (for presentations, either in the boardroom or better viewing of photos and videos), USB A (because thumb drives), and for my specific work, an ethernet jack, are all required to do my job. Also magsafe power is a lifesaver.
I'll be holding onto my 2014 15" until it's cold and dead. And if Apple still doesn't have a suitable replacement, Lenovo likely will still have great pro laptops.
