Really? What games have you found that the trackpad has worked well on? I haven't played too many PS4 games, but every game that's implemented that trackpad hasn't done it in a way that I feel like it's been to my benefit.
So far games haven't really taken advantage of it, except to gain two more buttons (it can sense which side you're pressing down on). But the built-in keyboard uses it, for example, which makes typing a breeze.
The potential is there, it's just up to developers to actually use it. Keep in mind that the PS4 didn't even have a single truly good exclusive game until Bloodborne came out recently. It's taking this new generation of consoles a long time to really kick off.
