People saying "it was so ugly!"
Man, have you seen Titanfall XP? I'd take the glass-like, skeuomorphic stuff from Vista over the garish, bubbly language from XP. Hell, I went from Windows ME (!) to XP and thought the latter was ugly.
In any case, beyond the visual stuff, never had too big of a problem with Vista. My laptop with it died after a year and a half of use, but that was because (I learned too late) it was a problem with NVIDIA's model and I think the entire line of GPUs was fucking borked, not because of Vista itself.
