Hmmm... And what you indent to do with that data? There are roundabout 3000 devices in that list and an average user might not have more than 5 or 6 smart phones (I have 2) and maybe 4 tablets (I have one).
The device list gets updated frequently, almost daily (last device added: "Huawei, Ascend Mate7 Monarch"). You really wanna download all devices daily?
Having the list on the server and downloading only devices, I need ( I keep my devices at least one year), is better at this point.
