>>1514766Tech: iPods are essential, touch, nano, standard models, anything goes
Flip Phone of any kind that runs a Java OS. Or just any phone from that era.
PSP, PS2/early PS3 models. I'd say go for a PS Vita but the Vitas are so damn expensive.

>>1514778you could also add stuff like Magical Girl Lyrical Nanoha (peak in my opinion), Melancholy Of Haruhi Suzumiya (Manga, Anime and Light Novels), Elfen Lied, Clannad, or if you want just go on MAL and search for anime lists from the 2000s/2010s. Its a rabbit hole.
If you want to go full on early 2000s vibes, I'd say boot up a Loonix VM and fuck around with themes and shit that isn't necesarily frutiger aero but does fit in the 2000s style.
