I regret buying a Vita...well, not really because it was a gift from my ex, but it's a dead system, while on the other hand the PSP has been my best buy/bang for your buck.

I'm sure some of you people bought the iPod killer ZUNE and just totally forgot about it..

And every third party controller i bought i regretted it almost instantly..

I kinda regret buying a WiiU, at least at launch. Thats a system I definitely should have waited on. I usually dont regret buying games, I have regretted buying season's passes though(several times I got tired of the game long before the dlc started hitting).

I kinda regret buying a 3DS. The only 3DS games I played are Fire Emblem Awakening (one of my biggest disappointment ever) and Persona Q (okay, but not that good either).

The only good (awesome) memory I have with this console is that I used it to play 999, but an original DS would have been enough for that.

Regret buying a Vita so early. I enjoyed it and still play it occasionally but would've rather waited for it to hit the dirt cheap prices we're seeing now

Mine would be the PS3, and Wii. The Wii I played only a handful of times since most of the games that came out on it I was not into. The PS3 was kind of the same way. Bought it, played a couple games, but never got into going back and playing it more since I prefer the Xbox ecosystem over the PlayStation. One system I truely miss, is my PSP. I used to play that system all the damn time when I was out and about. Miss my DJ Max Portable. But it was stolen from me and I never ended up buying a new one :(

I regret buying an LG Hombot. Thought that robot vacuum cleaners were already tuned since I didn't buy a first generation device. But that thing would become crazy on rugs, specially one I have with sharp black shapes. Was glad I could return it, even had to cover the shipping costs. Still not sure if I should try a Neato or Roomba... or just do the vacuum myself.

Vita.

PS3, GameCube, Saturn would be my 3 regrets, Wii U would have been a fourth, but Xenoblade Chronicles X and Mario Kart 8 made me feel a little satisfaction. I have been happy with every other console, but those three never really shone the way I thought they would, on top of being terribly disappointing. Microsoft is the only major hardware company that has never disappointed me, but to be fair, I've given them no opportunity to do so.

PS3 - cost a ton of money, and was a far cry from PS2 in terms of software. The main games I was interested in, like Final Fantasy 13, were hugely disappointing. Games that are supposed to be good, like RDR, just came off boring to me. I was pretty much convinced I had grown out of that kind of console gaming.

GameCube - similar tale to PS3. The games that came out for it reeked of derivitavity and inferiority when compared to previous entries in the series, or other ports/versions of the game. Games that were supposed to be great, like Metroid Prime, felt slow and boring to me. Others like Mario Kart and Mario Sunshine were painfully gimmicky. Plus, the controller was junk. The buttons were a jumbled mess of misshapeness, the triggers were noisy and springy (or difficult to find, like the z-trigger), the analog sticks were toy-like, and the d-pad was made for baby fingers.

Saturn - I didn't give it much of a chance, I only ever had 4 games for it, and barely played it. It was a collosal waste of money.

Wii U - again, just no games for it that are interesting. No triple A titles. I really liked Xenoblade, VC games like Earthbound, Mario Kart 8, so it is kind of like N64 where I was disappointed, but still not regretful I bought it.

I regret buying the PS3 two times.

360 was so much better.
