I don't regret buying my Ps4 because I know their will eventually be some awesome games to play on it, but I haven't turned it on since January. I should have bought an Xbox One first instead, but it was a $100 more at the time and I thought I was making the right choice. I really want to play Sunset Overdrive and Halo MCC.

There just wasn't enough games for it. I do remember buy it very cheap...I think it was $29.99 at the time.

Xbox 360... Hate cells, already had PS3 year ago, addicted to trophies, only finished Banjo & Kazooie on it

Well, I didn't technically buy it (my dad did), but definitely the PSP. I simply couldn't get into it like I had with past handhelds.

The Wii because I hated the controls so much it ruined my favorite series of all time. The DS after that because it just plain sucked.

Every single portable systems I ever owned:

Game Gear

Game Boy Advance

PSP

PS Vita

All of them, I get caught in the same thing every time, the people who have them rave about game x, y and z... I get caught in the hype... and bank it sits there unused!

Why?

I hate playing on such a small screen :-/ and the resolution is so bad on all of them (PSP was pretty impressive at first, but I got it late).

PS Vita TV...?

SEGA CD.    What else can I say. 

Sega Mega-CD, crazy me

Playstation vita
