You enjoy what makes you happy. You obviously chose a vita because you like what it offers. There is still time for vita to pick up yet. People are just jumping on the nearest hate train. I would like to see a system come out which doesn't get ridiculed by the media about how it is destined to 'fail' or forum trolls who claim to know what they are talking about.
You enjoy your vita. Eventually people will be joining you. Then the media will move on and bash the next system. Fact is the 'reasons the system is doomed' is more like'the reasons I don't like it'. Some people must see something in vita that I don't or they wouldn't be on the fence about it.
