The Nexus 6 hasn't been a big seller for Google, and that's likely due to its price. However, it's currently on sale now from eBay's Daily Deals for just $599. Not a huge deal, but still cheaper than what Google is charging. Not to mention, there's free shipping. The Google Nexus 6 features a 6-inch 2560x1440 resolution AMOLED display, Qualcomm Snapdragon 805 processor with 3GB of RAM and 32GB of storage. As well as a 3200mAh battery inside.
