12.2 is and awesome device. I have the Note 10.1 and Note 3 also. I bought the 12.2 after the 10.1 as 10.1 is not big enough for business whereas the 12.2 is perfect. 12.2 benefits versus 10.1....display resolution (beautiful), charging location, USB 3.0 connector and new location from the 10.1, Samsung keyboard storage right onto the 12.2 tablet. Great for movies on the personal side, and awesome for business note taking and presentations on the professional side. 10.1 does benefit from easier to carry around for personal use due to size but the features listed above for the 12.2 are unique to the 12.2 vs the 10.1. 12.2 does have dual band WiFi 802.11ac
