-Shit battery life.
-Small, low-res screens.
-Borderline unfinished hardware design.
-$40 Rehash games.
-$20 band-aid second analog add-on.
-Obvious superior revision coming next year.
-Garbage "online," which is barely even there at all.
-Wasteland eShop with old late 80's Gameboy titles.
-3D effect that is ruined if you don't hold the system perfectly still, and if the perfect position. Negating most gyro or AR based gameplay.
Ouch. Painful summary. Sadly true.
