It’s small. It’s wireless. It prints. It’s 100$ and it’s awesome.
It does however, come with a plethora of drawbacks that just might want to make you wait a little until they come out with something just a bit better. So let’s see… Its wirelessness is of the infrared kind, as opposed to the arguably better bluetooth. It accepts files with a size of up to 900kb only. A 10 pack of the special paper needed to print goes for 6$. The CR2 lithium batteries will need to be replaced after 130 prints. The actual thing measures about 4 inches by 5 inches by 1¼ inches and will print pictures about the size of a credit card.
So yeah, not a whole lot going for it, other than its ultraportability and potential for immediate gratification. Still neat though.
