LEGO. I'd say on average developers/engineers like LEGO more than non developers.<p>I'm a sucker for furniture that I can take apart and put together again. There's German brand (<a href="http://www.floetotto.de/en/products/profilsystem/" rel="nofollow">http://www.floetotto.de/en/products/profilsystem/</a>) who make the same product line since 30+ years. Impressive resell value on ebay, I bought 20 year old spare parts. Same for <a href="http://baltonliving.de/baltonbroschuere_e.pdf" rel="nofollow">http://baltonliving.de/baltonbroschuere_e.pdf</a> and some product lines of IKEA (less durable). Maybe it's the adult version of LEGO?
Linux, docker, emacs, GCC, golang, PostgreSQL. They are the best in class tools, making me much more productive and interested in software than any paid product ever could. They are free, as in beer.
I love Airbnb - simple, straightforward and easy to use. Their app on the iPad needs some work though, but other than that their design is quite simple and easy to follow. Their customer support is awesome - the other day I had asked my renter to check if there was a key and she didn't find any. A few weeks later, when she found it, airbnb immediately reached out to me to let me know something was up.
Thanks the the initial feedback. Let me clarify one thing. I am more interested in the services/tools that you use as developers during the development process. I'm just trying to get an idea of what companies/brands are doing a good job at capturing the developer community.
