There are some cons. If you aren't capable of rooting a device, or comfortable with learning how, then the S7100 isn't for you. When mine arrived, it was mostly in Chinese, had no access to the Android Market, and the home screen looked like someone had thrown up a bunch of icons. I updated the firmware to the English version, installed the Market, and created a second home screen with ADW Launcher. I would consider all of these steps to be necessary to make this tablet your own.
The emulation runs well enough, with occasional drops, but nothing that'll really keep you from enjoying the game. The one big knock is that there are no shoulder buttons, which effectively makes some games unplayable. For some folks expecting to play Goldeneye or Metal Gear Solid just how they remember it, you will be somewhat disappointed. The battery life is ok, something like four or five hours. As an added plus, the HDMI out works great for both games and movies with no hiccups at all, even if it's a bluray file. So you can use it to play Tekken 3 on your TV, then switch over to watch Tekken: Blood Vengeance. All this for less than $180.
For the price, this thing is boss. Customizable, capable of doing just about anything you throw at it, and surprisingly quick; the JXD S7100 hits the spot as far as alternatives for buying one of the emulation consoles (Geimei A380, Wiz, Canoo). If you do your research, you'll see that this is the best one of the best options for a portable gaming tablet or an emulation console.
