Definition: Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.
Input: I have a Mac and didn't think about it until the kit arrived: There was a disk inside which made me concerned that I would need to install or set something up on a PC.  Turns out I didn't need it - only to plug in the usb modem and wait a few minutes for it all to sync up by itself - and that was it.  I did use the enclosed instructions (on the disc - readable on the Mac) to implement a secure network (so other people don't use up your 3G allotment).
Output:
Positive Review
