Among other things, I was one of these dumb people that bought a Bada phone, back then (Wave II). Hardware-wise it was a wonderful phone. But software wise it was abandoned by Samsung in a matter of months, IIRC. Never more.
Also bought a middle category Samsung TV a few years ago. It came with an awful IPS panel with a contrast ratio worse than an LCD casio watch and bad luminance. My fault for not swapping it in time. Nonetheless, I didn’t expect such a crappy TV from such a brand.
