After I purchase the trial, do I have to redeem it on a PS4 or can I do it on Vita? Because when I go into PSNOW for Vita, everything is a la carte instead of subscription based.
The trial is for PS4 owners only....it just also works as a 'bonus' for PS3, Vita and PS TV owners if those systems connected to the PS4 with the PS Now Trial have the same PSN account (effectively activating the trial across those systems PS Now Apps).
As of right now? The PS3 PS Now app is completely broken (my Beta PS Now App doesn't load right at all now), the Vita PS Now app still is the 'beta' version with no subscription option, and the PS TV version likely is dealing with the same problem the Vita app is dealing with.
I have no idea why Sony didn't make the trial a purchasable thing on PSN but....this is Soony we are talking about here :l.
....If you have a friend or family member with a PS4, see if you can talk to them about this and ask about using your PSN account on their PS4 to 'activate' your PS Now trial on that, with that activating it for your PS3, Vita and PS TV. Then deactivate your credit card from your account in the PS4 app and remove your account completely from your friend/family members PS4.
I know that sounds completely stupid....but I see no other work-around for this unless Sony puts out an update for the Vita, PS TV and PS3 PlayStation Now apps to support the subscription system

I'm sorry if I cannot help with this man; I wish I could try this on my Vita too (do not own a PS4 yet). At the very least.....you can see what interests you from the new PSN sales
; lots of great games on sale for the PS3 and Vita (check out the PS Blog post on the sale and the thread of the sale on Gaf to find out more about it). If you never checked out Persona 4 Golden, give it a shot
