I for one have been using the preview builds since they started and they are certainly getting more stable. I just hope they don't have to rush or hold back on features or stability with the release now under two months away.
Defiantly love the front facing speakers, just seems like the common sense thing to do.
Shame about no wireless charging though, it's a very convenient feature that is missing.
