Just been sent a 18 month old device. The z30. Fantastic fast os and great email ecosystem. The Hub an extended version of the Q10 is faster at delivery than Android or IOS.
It takes me back to the time I got a Z10 in February 2013. Was great to get a new phone and start from scratch. There were 2 software updates that year. But now we are on 10.3.2 .
Will update as to the experience.
