Going to stick with portable systems, because a box is a box is a box, even if some are cooler than others (PS2 slim with attached screen, and N64).

#3 Gameboy Advance SP

Loved the compactness of the clamshell design. So much more portable than other systems at the time.

#2 Steam Deck

Windows games on a Linux handheld, plus it runs old games that Win 10 can’t.

#1 PlayStation Portable

This was and will always remain my favorite gaming system. So many great games, movies, a cool disc/cartridge hybrid media format, SD card support for all sorts of stuff, custom firmwares… man, such an amazing system.
