Another double post, but meh.
It seems with the slim out, accessories for the slim are now coming out. One that interested me when I first looked at accessories for the old model was the
Nyko power grips. Now, I haven't had THAT had much trouble with holding my Vita, but there was one night where I was playing it for a while and the next day my hand felt a bit strange, so I thought about getting a grip for longer play sessions. I had seen grip accessories for the old model, but I knew they weren't compatible with the slim, so I figured wait a bit, and new accessories would trickle in. I had held the Sony trigger grips in my hands for the old Vita model, but they didn't quite feel right to me. I like the idea of looking and feeling like an oversized Playstation controller, but the oversized aspect of it doesn't quite sit well for me and didn't feel too comfortable in my small hands. I researched other grips online, and ran across the Nyko model, but like the trigger grips, it wasn't until recently that a slim-compatible model was released.
This week I saw the new trigger grips for the slim Vita in the Best Buy in the building where I work. So I quickly went online to see if other grips were trickling in, and indeed, the Nyko power grips for the slim were out. I couldn't feel them ahead of time as I couldn't find them anywhere around here, but I decided to take a risk and order them. What's cool about them is that it has its own battery pack in addition to the Vita's, that at least according to the instructions, is pretty smart about how it interfaces with the Vita battery. The point is for it to further increase the Vita's battery life span, and as you all know, I'm a big fan of good battery life.
Received them in the mail yesterday and I could hold them. They felt a LOT better than the Sony trigger grips when simply in my hands, at least to me. The instructions recommended fully charging the grips before putting the Vita in them, so they're charging right now, as I got home pretty late last night and didn't want to leave it to charge overnight. So I haven't yet actually used them with the Vita. Once they're charged, I'll try them with the console, but I have a good feeling right now.
