Review of the 3ds
Pros: You can take it wherever you go
Dual Camera
Wi-Fi
Internet Capabilities (YouTube, Netflix, etc) You can create miis similar to the Wii U
When you walk 100 steps, you can redeem a play coin in the Mii Plaza
Long Battery Life (if you charge it)
Cons:
You can easily lose your pen/stylus
Galaxy 3ds color easily blends in with tables, makes it harder to find
You can easily lose the 3ds itself because of its compact size
3d setting can cause eye problems if you don't adjust it correctly
Overall:
I would say that the 3ds is pretty cool, but bad things could happen at the same time if you are not careful. I like that when you download Miitopia and beat the whole game, you are awarded with a Villa where you can store 90 more buddies.
