x264 - 8-bit vs 10-bit?

[minaust]

Howdy everybody...

I've done a bit of homework here as to the pros and cons of 8-bit versus 10-bit encoding, and here are my assumptions:

1. 10-bit encodes will play only on my PC. Nowhere else.
2. 10-bit encodes don't have a banding problem endemic to the 8-bit encoder.

As to my needs, 1 is no problem as I use my PC as a video jukebox, and I haven't encountered 2 (yet). Is there any reason to NOT switch to 10-bit x264? Are my assumptions correct? Any more pros or cons I should know about?

Thanks for any replies.
