If I could get away with not having a cellphone, I would honestly much prefer to not have one. Unfortunately, the modern job market and my wife wanting to be able to reach me make it unlikely that I could do so without suffering some fairly major issues.
Initially, I quite liked the idea of being able to consolidate multiple devices, like an e-reader and music player into a single device, but I've really come to resent the expectation that I should always be available to contact at all times.
If I could ditch mine, I'd really rather just have some sort of portable device in a similar form-factor that could play connect to WiFi, play music and podcasts and work as an e-reader. Bonus points for some sort of offline map/navigational capacity. I don't want to get texts or phone calls, and only be able to access email and the broader internet when I'm somewhere with WiFi.
I like to think I'll eventually get to a point where I can do that without having to worry about being unable to get jobs for not responding quick enough. Unfortunately, it seems like more and more things are trying to make cell phones an unavoidable aspect of participating in society, whether it's banks only offering OTP texts for 2FA, or so many venues no longer even offering the option to print your tickets at home, but instead requiring you to display your ticket in an app on a device with an active data connection.
I certainly wouldn't say it's trashy, but there are plenty of others who look down on it because they're racist and/or insecure. Plenty of people will say stuff like "You're in America, speak English!" if they hear someone having a conversation in another language. Hell, I grew up a monolingual English speaker and learned a couple other languages as an adult, and I'll get dirty looks sometimes if I'm talking to my coworkers in Spanish, or my sister-in-law in Portuguese. Some people assume that if they show up, whether they're part of the conversation or not, you have an obligation to switch to English as soon as you're in their presence. There are a lot of ignorant people out their who try to mask their racism with a veneer of "proper etiquette" to force others to change language.
If I'm talking with my coworkers about what we're going to eat for lunch, and someone gets pissy about hearing Spanish because they assume we must be talking shit about them, that's not my problem.
