Echoes my feelings too. Paid shitloads for it on launch day, but has been money well spent. Playing in bed, or generally when I can't get on the tv! Proper games too. Fantastic machine, and with Plus, so many games to play and so little time to play them!!
Unlike other consoles I have bought (glares at Nintendo) I haven't regretted my launch Vita at all. Had so much good fun on it and am happy that my money was well spent. I don't think it has left my bag since launch, mostly thanks to EG.
Those deals these days are excellent. I shudder to think how much I paid for a vanilla one at launch.
