Palm Pilot is mentioned, but not Amiga Computers? For me it defined an era. Warez, games, hacking in assembly and Aztec C compiler. Too bad I migrated to MS DOS (yet Turbo Pascal was great), as Macs were unaffordable in Germany.

Edit: A good list anyway. AOL dial tone and AOL CDs. Lol. Spent countless hours chatting to strangers on aol.
