I am a hobbyist furniture builder, I intend to always use dust collection. Is there any reason (other than brushless motor) to get the DTSC over the DTS 400? I would most likely get the basic and then buy the mains adapter. Any users of both want to shed light on other advantages of the new cordless.
 
Not sure what type of furniture you build or what specifically you will use the DTS400 for. I do own  the DTS400 (but not the cordless model). I, too, am a hobbyist - furniture, cabinets, etc. Three comments about the sander...

1. I love it...No vibration...A great finish sander...Smoother operating than my ETS125 with at least the same result (maybe better than the ETS125).
2. I bought it to facilitate sanding into corners. While it certainly does that, I don't think it quite met my expectations with regard to corners. You have to be careful not to damage or wear out the the front point on the pad when corner sanding.
3. For sanders, I have never seen the need for cordless. You're tied to a vacuum anyway. Might just as well be tied to an outlet also. I use a Festool CT with an overarm and hose/cord combo. With that setup, I see no advantage to cordless. A good reason for the cordless model would be if you plan to use the sander at multiple sites or don't have handy outlets in your shop.
 
I use my sanders a lot and they're always connected to one of my Festool vacs because I simply abhor not using DC. So I myself don't see any reason to go cordless.

I do think it would be useful to own one, there are always these difficult spots that are hard to reach with a corded type, but it would always be an "extra" sander for me, for special occasions, and not one of my main sanders.

But you'd be wrong to consider the DTS just for corners, it is for all sanding work, and you'll see if you own one you'll start to use it for everything.

 
I've used a DTS 400 and a Rupes Ls 71te with their respective filter bags and they were a lot better than I expected. I would normally hook up my vac as well but I can definitely see using a cordless version for small jobs where it is convenient.
 
I would agree that the DTS400 is a great all-around finish sander and I really just use it that way most often, especially when I have to sand something that requires general finish sanding as well as some corner sanding.
 
I know you said you would always use dust collection, but the greatest advantage of the cordless is where there is no mains power available (duh!) - I bought the DTSC specifically for an outside job that would have needed 30-40m (that’s approx 100 - 130’ for the colonial cousins) of extension leads*. Because it was outside I didn’t bother with dust collection but just relied on the supplied dust bag and a face mask. It worked brilliantly; the battery was good for 30 minutes work, and the recharge time was only 25 minutes, so virtually uninterrupted work was possible.

Since then I have only used the batteries when working outside where dust collection is not so much of an issue. Indoors I have only used the mains adaptor because with a dust hose connected you might as well use the mains power. Although it is a great finishing sander, it can be quite aggressive with 40/60 grit.

*My wife calls extension leads “socket lengtheners” which I think is a much better name
