S20 ultra. My SO got it for me at launch because he thought I deserved a nice phone after getting me a 150 dollar one that lasted me a few years. I have tiny hands yet I have no issue with the size of this phone lol.

Best qualities? Still runs great, unlocked so no bloat, real cameras instead of the fake one on my old phone, Samsung dex, oled screen, not a scratch on it and I haven't used anscreen protector in for years now. Has a large battery.

Worst? Hmm... at first finding cases that protected the screen properly because of the edge was hard. It took getting used to the whole curved edge though now I think it's weird to use one without it. It gets hot when gaming so I avoid anything too intensive. It's older and I don't know how much longer it will be supported.

I previously owned a Huawei honor 6x lol... Before that it was just a flip phone and before that an iPhone 4s which I still use as a clock.

My current phone is the best as it does everything I need, the worst is the iPhone mostly because it came with almost no memory and no way to expand it and every os update caused it to run more and more out of memory. Also it was tiny.

I upgrade when the phone I have isn't worth keeping. My last phone had a spicy pillow and even though I tried to replace it the phone was so horribly glued together it was impossible to open up with regular tools. It was cheap anyway.

I have a portable Nvidia shield that is so out of date its unusable. The battery is dead. I might repurpose it though. I don't own any apple products beyond my initial iPhone as they're too expensive. I have have had the same fitbit since 2019 or so and I got a certificate from work that paid for some belkin wireless earbuds, beyond that and a pair of skullcandy wireless earphones I don't have much else.

My windows devices are all computers.
