Definitely wise to try before you buy.
I played around with the Fold 7 in stores enough that I feel the TriFold will be very familiar. The TriFold is basically an extension of the Fold 7 -- same front cover screen, same thinness, same cameras, same OneUI, same no S Pen, etc. And by most accounts, battery life is quite good on the TriFold. Hopefully I don't regret it, but I'm not feeling that will be an issue.
Today has been busy at work. Once I get free I need to dig more into whether or not Samsung VIP Advantage truly extends Care+ to the TriFold or not.
