Is anyone else excited about this feature? All the reviews I've seen for this device talk about the bigger battery, the water resistance, the AMOLED screen, the finger scanner, and the heart rate sensor. Occasionally someone will mention the download boost feature, but no one talks about the new 2x2 MIMO feature. Not only does it help increase download speeds, but also helps to improve power effeciency. I think this is a pretty big deal, but I guess no one else does. Here's more info for those that want to look into it. Broadcom Demonstrates Innovations in Wearables, 4G LTE, 5G WiFi 2x2 MIMO, NFC and Location Technology at Mobile World Congress 2014 | Broadcom
