dont feel too bad; there are some people that believe the PSVita is still going strong & healthy despite sony themselves all but admitting it's a dud
Obviously Iga is among those who think it's worth while.
The nice thing about the vita is it can be a slow burn because it's a powerful enough handheld to withstand time before becoming obsolete. Also as I have told you countless times, it is an extension of the ps4. It is more than just a hand held gaming console. It is a satellite.
If you owned a vita and saw how often new quality games are being added you might have a better idea of how wrong you are. Almost every time I log into the store there are new interesting games. Mostly japanese, but that's more than cool with me.
The wii u was basically designed to be obsolete. And without 3rd parties showing any interest Nintendo has had to carry their own weight. Clearly it hasn't been viable because they are already moving on.
Hate to break it to you, but while the vita isn't a huge success, it seems to be doing just fine. And I'll be enjoying Bloodstained on my beautiful retina display. That's a success to me.
