You left out one major thing, as this is Audioholics.
I think those are both good summations.
Without stating what comes ware or with what (I have not played critically with enough different units).
Issues with BlueRay players:
- Compatibility (not all units play all disks and standards tend to get updated: so there's reason you might want something with both the ability to upgrade *and a company that actually provides ongoing updates*
- Interface / load speeds / other ergonomics
- Transcoding: Blueray does not store its video in HDMI format. Even with digital outs, there is a digital-to-digital conversion of data (BlueJeansCable has a rant on this in their FAQ). Not all players are created equal in regards to output.
- Durability: Not all electronics are equally built to last.
- Reliability: Particularly on the very low end: Does it tend to have trouble conforming to HDMI 1.3a 100% of the time? Do the connectors tend to make poor connection? Is the voltage consistent over the cable? Really, these errors would actually be "poorly built" not just "inexpensive", but seem likely to be a real concern in a world where WalMart recently had to recall a DVD player they sold because it tended to burst into flames.
