If it's zero-g, why does it need a stand? <_<
Are a lack of speakers really a con though? The speakers included in monitors are usually pretty bad. If you want speakers of that quality, you can probably find a set for $10 somewhere. Most gamers will likely be using either a headset or better speakers anyway.
Perhaps more worth noting would be that the limited FreeSync range means you won't get LFC to keep adaptive sync working when framerates dip below 48 fps. And while you might consider the resolution to be low enough to still get decent performance on "mid-priced" graphics cards, we're still talking about 2.4x the resolution of 1080p here, or nearly 35% more pixels than 1440p, so even with a $400 graphics card, performance is bound to dip into that range at times in some of the most demanding games with the settings turned up.
