For $60 (taxes, fees included) you get unlimited calling, texting and 4G data. In the D/FW area I usually average 10 Mbps download speeds on my N4 (that only has HSPA+), my wife can gets 15-20Mbps with her MotoX (4GLTE).
If you are using it as a hotspot though, hotspot costs an extra $5 per month, and that is limited to 2.5 GB per month 4G. The phone would still get unlimited though.
