In typical organizations, you always have a grizzled backend developer well-versed in creating REST backends in Java and a frontend developer well-versed in whatever. So you play to their strengths.
The last "new" computer I bought was a laptop in 2011. A 13-inch Macbook Pro with a 2nd gen i7. After that, I've always bought used, as the place where I'm in right now, the people prefer the newest shit, so I happily buy their used laptops for cheaps. Mind you, these are T480 Thinkpads that people are selling for very cheap in order to buy the latest.
Alrighty then.
