I tend to use the cheapest Android phones that I can get my hands on which don't ship with malware from the factory. Yes, this also happens. Then I use them for as long as I can, and I dread getting a new one.

Note that I use lots of computers with Linux and I genuinely enjoy upgrading them. But the experience and perks are completely different. Computers get years and years; even potentially decades; of security updates. I'm also more in charge of how the computer works and what it does. They're also easier to fix and upgrade. All of these things make them a more compelling market to spend money in than the smartphone realm, where all I need, and all I'm willing to buy, is something that is just good enough to get me by.

I think with Android, the lack of updates is the biggest turn-off. I get years of updates on the computer whether it is low-end trash or a high end monster workstation.
