If talking about ETS against T3 i don't think it fair..But technology always steping forward we might have to follow or we disadvantage..
But if it can be Cheat???I used to worked with electronic and programing ..worrying that it can be cheat..Every one use to go to store and see cashier scaned you goods before,Now what did they do if they can't carry your item on the scanner..They using there hand hold scanner Right...And those hand hold scanner don't even touch the item they can scaned 4-5 feet away.
As the technology steps forward i worry about some body smart or know some body smart enough to find the way to scaned there birds 100 feet??? may be 20 feet away.
Soon or later the price of ETS will droped(just like camaras..TV's....) and evey one will own one.
