Computers:
In 1986, step-dad took me to a pub that had an arcade game "where you had to collect the cherries". Turns out it was called Mr Do. He kindly got me for Christmas that year a BBC Micro B+ model with Mr EE which was pretty much like-for-like. The Beeb was pretty good for arcade ports
If you're talking PCs, then my first PC was 1999, so aged 20 and pretty late on the bandwagon. P II 350MHz. It was all about Age of Empires II, the Sims and Final Fantasy 7 and 8.
Parents got their first PC in 1991 and it was all about a WW2 flight sim called the Final Hour.
Phones:
Parents got their first phone in 1994. They were still brick phones back then, but they were nicely surprised when the handset was actually a bit smaller than a normal telephone receiver. 1994 was an era when it was only 1 mobile phone per household and was used for emergencies only i.e. car has broken down.
My first phone was year 2000, aged 22, so late on the bandwagon for me as with PCs. Nokia 402 which was Orange-branded. Think the proper title was a Nokia 5110. With the blue cover. It was a pretty old model too for 2000. More like a 1998 model or a hand-me-down model if 2000.
To compensate in 2017/18:
Phone - Sammy S8+ with a sexy 6.2" screen, so I have pretty much caught up there
Computer - Lenovo laptop with i7-4720HQ (Passmark=8025), 16GB RAM, GTX 960M 4GB dedicated, 500GB SSD, so caught up there. Dell Ultrasharp 2415M too
