First PC was from holidays 1989 (well, it's older than that, but my dad got it for "cheap" from his company as they were upgrading to the brand new 25Mhz i80486 that just came out)

• Intel i80286 with 12.5Mhz clock speed
• VGA GPU
• 2MB RAM
• 40MB HDD
• Joystick port (always wondered wtf this was doing in an office PC from a bank)
• 14" 800*600 screen
• IBM Type M copy keyboard
• Mouse with 2 buttons
• Needle printer for endless folding paper.

But then came the Parity Boot B virus... and instead of disabling the machine, it totally boosted it, hence why all my diskettes at the time had it:

• 60MB HDD instead of 40
• 786KB conventional memory (instead of 640, extremely handy for DOS games)
• Suddenly had SVGA capabilities (256 colors at 800*600 instead of being limited to 320*240) for some reason
• CPU clocked at 16Mhz

Nobody ever understood why it was behaving like this when the virus was found. The best guess was that it unlocked the hardware from all limitations set by their respective producers to their max capabilities.

First computer was an Atari 800XL, though I barely used it

I still love the design of the computers back then when they were integrated into the keyboard. Always makes me sad that you don't see those anymore these days...

Coloured keys were exactly why liked it so much - most other computers from the era were beige or grey, this one stood out.

I'm guessing you would prefer Schneider version, it had all colour keys replaced with grey keys.

Atari ST looked really nice, though as Amiga 500 owner, we used to be fairly often quite harsh on Atari ST and PC owners in late 80s and even '90/'91.

Well that was until we saw Commanche: Maximum Overkill, Ultima Underworld and Wolfenstein 3D on PC, all in 92. That changed...everything.

While the Atari ST did look very good (as mentioned, I'm a big fan of the form factor), esepcially the F-keys, but the keyboard quality itself was atrocious and more floppy than a floppy disk. It was a cheap membrane keyboard masquerading as mechanical keyboard, and from the start it wasn't very good for typing anything consistently. Had Tramiel not cheapened out  on this, it could have sold quite a bit better, as it was one of the main drawbacks of the ST line.

Also, I never understood why they removed the arrow keys and pushed them upwards...

Also, not to forget the super-odd placement of the Joystick and Mouse ports UNDER the keyboard.

ST's main competitor was Amiga, and let's face it, Amiga was better.

That said, ST found its niche in music industry - it was MIDI sequencer machine for quite a while in lot of studios, and both Cubase and Logic originated on it.

Tandy 1000 HX.

Got it in 1989. 

8088 7.5 mhz processor. No hard drive. 16 color monitor. 3.5 inch low density floppy. 256k of RAM. It ran DOS.

My parents had bought me an Amstrad CPC when i was a little kid and a Pentium III when i finished school.

I think i was 5-6. I got some PC that could barely play music but i loved it. Ofc didnt play games on it, just music but i used to spend whole day just listening music. Later i moved to console with 360 and i didnt own PC till 2020. Now i am just PC, PS5 (will most likely sell it soon) and Switch

ZX Spectrum +2 back in 1990.And i really ummed and aahed about that recent ZX Spectrum next kickstarter but in the end couldn't justify it, just got too many bills etc at the moment and honestly I have enough to play on PC.Main issue is lack of time nowdays.

My first laptop was obtained during 2009. It had an intel Atom processor, 160GB HDD, and 1GB of Ram. The screen was 10.2 inches.
My first desktop was obtained during 2015. It had an i7 4790k, 160GB SSD + 1TB HDD, 16GB of Ram and a GTX980Ti.

It was the PS3 that first gave me internet access thanks to its browser. I spent almost my entire life as a minor without a PC, phone or internet.
