why would you want to pay ~$200 for asus?
because Xtion
1) is smaller
2) consumes less power
3) does not require power supply (except USB)
contro analysis
1) lower drivers quality: that it not a problem if used as "LiDAR"
2) does not work with some USB controllers (especially USB 3.0): it may be a problem with some USB-hub or linux embedded boards, so you have to check it out
3) no motor, it allows only manual positioning: not a problem, in my application the unit needs to be mounted into a fixed holder
