Yes. I currently have /e/os on it. I dunno how long devices are kept up to date with that. But if any of the OSes are no longer maintained you can hopefully find one that is. So it's possible it could last even longer than the official Fairphone android version.
I could however see that tech may change enough that a ~10 year old phone may need replacement regardless if you can buy replacement parts.
I feel like this phone should be good for most users. Most people don't need to take super high quality photos or play demanding games on their phones.
Sure it costs a bit more per performance, but I think it is gonna be worth the price in the long run.
I have a FP4 that I plan to have until end of software support. I will likely have to get a new battery in the future, but that's a breeze since it takes a minute to change and it is affordable, especially compared to many phones that are basically dead once the battery is bad.
Cheapest I could find in Sweden. Around 10€. I think it is 3GB data and unlimited calls and texts. Whatever data I don't use stacks up for a year or somesuch. I have WiFi at home and the office so I don't really need much data. I would go for a cheaper plan if it existed.
Sencha Fukujyu. Loose leaf green tea with no added stuff. 70 degrees. Reuse leafs throughout the day. Brewed in a kettle that allows proper expansion of leafs.
While not really a budget tool per say, I'd recommend checking out Beancount if you are looking for a power tool and you are comfortable with a bit of Python. The only really manual steps I have in my setup is downloading transactions from my banks and categorizing any transactions that the machine learning plugin fails to categorize.
I feel like there is going to be a disproportionate amount of people not using a standard qwerty keyboard that replies to this :)
I use qwerty on a standard 100% and another split 60%. I am trying to switch to ortholinear split Dvorak, but haven't been able to design a keyboard I am comfortable switching to full time. I would also need two of them, one for home, one for work.
I have never ordered something from Amazon. It was introduced in my country a few years back, but it isn't really that good of a site (at least the few times I have visited it).
Like many here, I do not want to support a monopolistic company like Amazon. Luckily I live in a country where I have better options. I tend to buy things from plenty of well rated sites. Environmentally conscious sites if I can.
I could see myself buying from them if there genuinely isn't another option and it is something I really need, but that has yet to happen.
I had an issue where one keyboard (worked with another one) worked in bootloader, but not when entering the encryption password after that. I believe I solved that by moving keyboard earlier in the module list in mkinitcpio.conf. Maybe something similar would solve your issue?
I have basically the same thoughts as you. The reasons I can think of is:
Fairphone 5 has 5 year warranty. Sure that's not 4, but the title makes it seem that 4 is longest out there.
You seem to have a lot of recommendations already, but I just wanted to mention beancount as well. It's a decently powerful plain text accounting software. Not sure if it does invoicing.
For me it has been good because I think it is fun to hack some new functionality together that I feel missing. E.g. parse pdf receipts and break down transactions into postings based on what is in the receipt. But it you aren't interested in simple Python programming, I'd probably not recommend it.
Being able to easily version control it using git is really helpful when you are trying things.
I have been satisfied with beancount. https://github.com/beancount/beancount and fava as a ui. It's text based so it is easy to automate imports and exports. It can seem daunting at first to create importers in Python, but it's pretty basic scripting.
Text based accounting lends itself well to easy experimentation with version control.
I tried gnucash for a while, but it felt so slow and not flexible enough for me.
