Choices of the Gadgets

It is closing to the end of the Financial year. I am still running for ideas to spend my this-year's gadget allowance. Here is a shortlist.

• self-flying hover camera. (i am not a selfie fan; so still thinking GoPro is a better choice.)
  
• programmable robot (something i found out from an Apple store in Shanghai, which is quite abnormal for Apple stores elsewhere).
• water-proof earphone (just because i like water sports). e.g., https://www.wareable.com/hearables/bragi-dash-review
• electronic skateboard (my friend recommended me this https://www.evolveskateboards.com.au/)
• a curved UHD monitor (a conventional and boring option)

Now the main problem is, as always, budget.
