Wow, this brings back memories.
The first computer I owned was a Sharp PC-1251. I carried it to school every day and programmed it to death. At the same time we had first a Research Machines RM 380Z and then a dozen BBC Model Bs at school. Messed about with ZX Spectrum 48k and Oric-1 at home before switching to an Atari STE - later upgraded to 4Mb and 40Mb Hard Drive. Over the years I had a couple more Sharps as well because it meant I could program anywhere long before laptops were a thing.
Longed to get back to Acorn, so I had an A3000, then a Risc-PC with a StrongARM and a 486-card. It was Windows PCs from then on, database programming on Windows 3.1 and DOS with Compsoft Delta-V and then Visual Basic.
I guess starting with the Sharp is what made me interested in mobile, so played about with various Palm-based pdas before windows CE and winding up here to be able to program them.
