So far what people who bought devices learned is that the devices are overpriced and it is much better investment to just buy BTC instead. By the time any of these devices come out, you would be lucky to make 3-5 BTC with them at most. Many will regret not buying BTC as an investment instead. There is no way for consumers to make any profit as long as manufacturers make huge farms with their new devices.
The game is rigged, your device immediately becomes worthless after release. This is why all the companies are having some pre-order scheme going on. It is just too late when you figure out your mistake.
So, why buy the device and bother listening to its noise when you can just buy BTC and look at it's value rise? I would only buy from a company which can ship the device the next day.
So, long story short, no I won't invest in these devices. Also not investing does not mean that you are out of the competition as long as you have BTC. You can let those companies compete with each other and cause increase of BTC prices and make more profit that way. (and if BTC crashes, it wont help if you have a device or not anyway so all the same...)
totally agree, we learned the hard way. We get paid off in 2 to 3 months in $ not in BTC.
If the hardware is not delivered the second day, don't buy.
I also will start preferring Mining contracts (that are alive and hashing).
