In the newly deployed GetWindows10 app, there's an option to "Check your PC" - when I choose this option on my Inspiron 14z, I get:
Windows 10 will work on this PC
This PC can be upgraded but there may be some issues.
Devices
These devices aren't fully compatible with Windows 10
AMD Radeon HD 7570M (with a bluetooth icon beside it??)
You'll experience problems with your display
These devices might not work correctly after the upgrade
Bluetooth Server (with the same bluetooth icon)
Intel Corporation
I'm not inclined to upgrade if it's going to result in problems either with my bluetooth OR my display. Any change that Dell will release updated drivers to address these issues? Other options?
