I know not everyone is into hand held gaming and some would like to argue how smart phones and tablets are a growing market.
This is just simply for owners of either or people who want to upgrade to one.
I have a 3DS XL and the Vita. These are two fantastic systems and while personally feel last gen in hand helds was the best. This one has potential to be better.
3DS is a great system that is plenty powerful. Revelations will show that or Kid Icarus. Eshop is pretty good but still leaves much to be desired compared to PSN. 3D really works but is gimmicky and doesn't add much.The sliders analog is really nice. tho some games might be nice to have a second one. But that rarely happens. It already has a decent library. From the 1st party Nintendo games like Mario,Zelda,Fire Emblem to some games like Metal Gear,Kingdom Hearts,Tekken,Dead or Alive,Street Fighter,Code of Princess,Shinobi Etrian Odesseey and more. Some downsides are surfing the web is a pain. It's not a very good media device for movies or music. It has Netflix but it's slow and SD looking screen. Upside Includes a SD card with every system. Can upgrade to 32GB if you want.
Vita is like PSP in 2004 a marvel at what they packed in a pocket sized device. Internally and externally a really posh(can an American use that word?) system. Vita gives some clue how nice the PS4 might be. The touch screen is very responsive. The screen is OLED and it looks HD. Best looking screen on a hand held device thus far. The system is nearly limitless in what devs can do. Not just in power but the touch screen the touch pad. One game that shows the touch screen and motion really well is Gravity Rush. Also it uses real analog sticks. Dual analog. So Sony thought the hardware out mostly pretty well. Has a nice and simple but classy UI as usual from Sony. Biggest downside to me is the memory cards. Overpriced.
Now if concerned for selection of titles. It get's more flack than it deserves. It has Uncharted,Gravity Rush,unit 13,Persona,Sly Cooper,Mortal Kombat,Street Fighter X Tekken,Virtue Last Reward. More on the way as Muramasa Rebirth Next Month,Ys IV,Dragons Crown and Final Fantasy X later not to mention all PSN games to download.
I have already said many times in many topics why I love Vita. Love both but prefer Vita as I feel it has the most potential.
