I browse the web on Fire TV everyday, so since I was told in this forum that the excellent Amazon Fire TV's "Downloader" web browser works in Android TV and can be downloaded from the Play Store, there was no reason not to get a Shield, aside from the very high cost (good thing they include the remote now or it would have still been no sale I think). So a few hours after the Google Assistant announcement on Thursday, I ordered from Amazon. No, I'm not affiliated with AFTVnews. Just enjoy the browser a lot.
I don't know yet if the 16-gig Shield being delivered today will come with the Android TV 6.0 software preinstalled, or if the Shield will have to download from the internet the one-gigabtye-large 6.0 upgrade. So I guess I'm wondering if the Shield has to upgrade over the net, would it be better to connect the 500-gig Samsung EVO 850 SSD before I turn on the Shield and connect the Shield to ethernet, OR would it be better to upgrade the Shield to 6.0 first, then connect the SSD? Is there an advantage to one method over the other? Thanks.
Doesn't matter. No advantage. Just fire it up, install all updates, let it reboot, then begin setting up your device. Or you can ignore the update for a later time to setup your device first. Either way the Shield will be the same at the end of it.
