Update: It’s even cheaper now.
On paper, the Nebula Prizm’s picture quality stats are a dead ringer for the Capsule’s. It outputs an 800 x 480 picture at 100 lumens, features automatic keystone correction, and has a built-in 5W speaker. However, it lacks an Android OS (you’ll have to use a streaming dongle, or something similar), and it has to be plugged in at all times, since it doesn’t have a battery.
Novelty aside, I could see it being perfect for a kid’s room, or maybe a bedroom or garage where you occasionally want to watch video, but don’t want to keep a TV. And at $85 (down from the usual $130-100), it’s practically an impulse purchase.
