Yes Mike, thats true. FP2 is amazing Idea. But a bad realisation. (Like usual). The Phone is expensive comparing to “normal” 08/15 Smartphones, but the Hardware has a bad quality. My Display was exchanged 2 Times because of Bright Spots Problem and after i got the second display replaced i got this bright spots 1 Week after …
I think this is no go for 530,- EUR Smartphone. No Matter how fair its produced. Fair produced is good - but it is not fair to the customer, when the Hardware should many times be sent round Europe.
Missing Jolla Cooperation was also a big Show-stopper for me. I loved my FP2, but without official SailfishOS and with such Hardware Problems i see no future between me and FP2.
Sony Xperia X is in this case, much, much better…
About Windows: Sony EMMA is needed just to check if your Xperia X has the latest Android Firmware installed, because of the binary blobs and the latest Baseband.
After that, the SailfishOS will be flashed with the fastboot script. You can do it from Linux, MacOS, Windows - whatever you want.
I think - Installing Virtual Box on Linux with Windows 7 just for Flashing is done fast. Afterwards you can simply delete and forget Windows…
