Well the jerk sold it to someone else and did not even bother to notify me. What a nice guy.

That stinks.  He should have notified you. How much was he selling it?

Don't stop searching for your beloved Vita, I have one since launch and the software has pretty much improved with a lot of nice features and apps. And there are a lot of good games available. Or wait until february after the Playstation event which will be mainly about the Vita. I think they'll announce a few new good games and perhaps a lower price.

I kind of let him know how I felt with a text message... so he knows that what he did stinks.

80 euros, would have been sweet with psn+. :/

I don't love vita, I don't even like handhelds. When I get another chance to get one for 80€, I will be jumping on it. Just to try it out.

I bet you will find another one down the road with the same price or slightly above like 90-100 euros.
