No, I'm going to argue that you gained more through possessing the device than by having the money you spent. Unless your stance is that only money is wealth.

Since money can be exchanged for goods and services, having more money directly translates into having more options to pursue your interests. If I had a bit more money, I could get an even better device, or if I was a billionaire I could pursue interests like making rockets, or any other fancy.

So, my stance is that money directly translates into increased opportunity in a capitalist society. Meanwhile, the relationship between capital owners and works is asymmetric where the capital owner keeps majority of the profit from the value that the workers create.
