She wants an Amiga.
lol I still have my Amiga 1000 running WB1.3 and I'll tell you when I first started using AmigaOS4.1 it immediately felt like home so I'll guarantee you she will IMMEDIATELY know she is using AmigaOS:hammer:
she used AmigaBasic and C so she'll be very happy running ARexx and C on a much much faster AmigaOS!
heck she can get a 'modern' Amiga that can run OS3.9 and she'll be happy lol If she has a good pension plan she can also get a 'real' Amiga with PPC and run AmigaOS4.1 classic:)
