Getting a bit emotional here whilst remembering....
Kicked off with a ZX81, when I started college in 81/82 then worked my way thoughvarious Spectrums, and then a QL before buying a Zenith 8086 cheap from Morgans - expanded the memory by buying and inserting DIL chips. None of this ram strip nonsense then. Soon learnt that in 88/89 Pcs werent much fun and bought an Amiga 600. Bought my first hard disk for the Amiga £250 for a 2.5" 60MB.
Bought an psion LZ64 second hand back in the late 80s, then upgraded to series 3, then 5MX.
Sold the Amiga and bought another PC in about 94. added soundblaster CD and sound card and a modem.
Best memories are
1. Getting a Token ring network and novell server (2.0a) at work in a tea-chest (had been stripped out of offices and rescued from skip!) I then figured out how to put it all together and network the PCs, and setup email in the room. I worked for Employment training in those days and we had barely any money for kit. at the time email seemed magical!
2. Setting up a headless linux based box as an Mp3 player attached to my stereo system back in the late 90s - had an LCD screen and IR remote, and I could put my CDs in the loft. Everyone thought I was mad. Also networked my first house at the same time.
3. My Psion 5MX was awesome. I bought the Ericsson SH888 phone with the modem. In 2000 I was uploading photos and reports using the setup whilst cycling the End to End. Near John o Groats met up with a party of school kids doing the same. they were using a laptop the size of a small suitcase and a digital camera with a 3.5" floppy disk drive and had to grovel a loan of a power socket and the youth hostel's phone line. I took the CF card out my camera, stuck it in my psion, and uploaded the photos over the mobile to my website completely wirelessly - The kids were amazed. It was a proper compute anywhere connected device.
I agree with @james51 - The N900 is great, but the 5MX was a legend - still have 2 and ne is one my desk in front of me. would love an updated one with wifi/bluetooth.
Been an exciting ride over the last 30 years - The next 30 should be a fun ride
