My working laptop runs Linux Mint and Win 10 on separate SSDs. 95% of the network engineering I do happens in the Linux environment. Bombproof.
The iMac I bought the end of 2010 still works, and I use it from time-to-time, but I mostly use my MacBook Pro which I bought about a year ago. My old MacBook Pro finally crapped the bed after 10 years, but at least the hard drive was salvageable.
In his spare time, my oldest son creates Fallout 4 mods, which he uploads to a website for people to download and use in the game. He has his own YouTube Channel that he uploads game videos to (Red Rocket TV). He also live streams on Twitch a few nights a week. He's 54, never took a computer class in his life, and taught himself everything he knows. He certainly didn't his brains from me.
