I really love my ASD, but the S9 does have some advantages that could matter to me that has me thinking of getting one for my other setup.
- Has Display Port - for connecting “older” or PC systems if needed
- Better Windows/Linux Support - again for those other systems
- Anti-Glare Screen. Depending on room this could be a big advantage.
- Height Adjustable. Again depending on setup this is an advantage. I’ve been thinking of getting an adjustable standing desk.
- Price - at ~$1K that is quite a bit less than the lowest price I’ve seen the ASD for (I got mine through Costco when they had it for $1299)
There are a few others that I don't really care about so didn't list. My advice is that if none of those matter, just spend the extra $ on the ASD.
