yes i dont know if anything of the bad experience i had changed in newer versions.
But i think hardware related parts at least are the same, you also see in many videos the reflection and you can expect that those videos are the ones with the least reflection after filming.
Regarding marker tracking there are different resolution of the markers…

For me only 3x3 worked relieably and i tested all kind of sizes and paper tyes.
Resulting in maximum 16 different markers.
In case of 4x4 it recognizes some markers correctly but some are “interchanged” and arbitrary randomly recognized.
5x5 ended up in a total mess in IDs that I received from the two test devices that i used.
SO i think the marker design was a good idea of them but implementation is bad and it doesnt hold what it promise.
There it would be good if you could use fiducial trackers instead but for that one would need to modify theire embeded linux…
There is another point for the marker tracking that has to be mentioned. It has trouble with certain type of material. some paper work better then other. reflective materials like plastic lamination over the printed markers are not possible.
in general the whole multitaction experience is a big trial and error.
Edit: But it has to be said that there is not much alternative on the market!
Fazit: You can go for it if the marker functionality is a absolute must (with max 32 marker). also only use it as a temporary installation and if you have enough time for taming the device. I recommend not to use it for permanent instasllation. Also the light setting needs to be carefully choosen to avoid direct reflecting light sources taking over the application.
Alternative:
A projector / camera system decribed here
http://reactivision.sourceforge.net/
is more relyable because you use one camera instead of a camera array.
you also have full controll over the tracking and projector calibration
edit2 there are some old threads about it if you look in the search:
The more i think of it the more problems i remember that i had with those devices,
for example i needed a lot of programming work to create logic that can counter weight false-touches, for example around the marker objects or at the palm of the hand or the whole edge area
