For disposables? Absolutely. There is no purpose for a screen. On a proper vape you need one to set it up for all the different coils that you can build or buy.
I have rechargeable vapes. I have never seen one with a screen and I am already annoyed by the the lights that they all have. I stopped using the one that vibrated because why the fuck would I want that? I just need a cheap nicotine delivery system and putting a screen on it is peak pointless tech imo.
Fair enough, to each their own. The screen is because these can work with so many different coils that you need it for setup. Also, a lot use replaceable 18650 which makes the device last even longer. I've been using mine for over 5 years.
From around 2016-2020 the most popular devices were just a series of incrementally adding more pointless shit, which is why it's like that. They're not that popular anymore.
