Sounds similar to using a lightning dock. Unless the dock is affixed to the tabletop/desktop, you'll pull the dock up with your iPhone. I'd say this charger is meant for people who would like another way to charge their phones while using it & easily disconnect when getting up.
Wireless charging pads aren't all that bad; you get confirmation of successful alignment via screen & chime. With MagSafe, you'd still have to get close enough to feel the magnets attract each other.
Someday we'll have Tony Stark tech that'll summon our device from anywhere to its charging station...
iPhone 3000? See what I did there. 😉
Until then, some will find spending $40 or $60 ($20 adapter sold separately) for the "attractive" assist worth it. 🧲
For others, a slight finger-nudge isn't that big of an inconvenience. 👉🏼
