Level of Tech as Physical Security?

 in many fields low and high specs have been used as a form of security. for example, in schools the math classes as you to buy scientific calculators. math class teachers ask their classes to buy 40 dollars calculators while it can be downloaded for free in the apps store for smart phones. this is physical security against cheating as the use of phones allow students to communicate. there has been incidents where students have cheated using their phones. students can use their phones for homework but has to use oversize calculators that comes at a price for tests. another example is nintendo's consoles and handhelds. consoles themselves are physical security for games. if the game is on a computer, anyone that is good on a computer can share the crack for the game and use it. but on consoles they use diferent firmware and hardware compare to the pc and the game data is not installed but left on the disk. unlike the sony or microsoft, their specs has stayed miles below theirs. this may not only be a plot to save money but a form of physical security against hackers. being low tech would draw less interest then PlayStation or xbox. but their consoles all have been exported and even emulated. all logical security for the devices are crack-able. many hackers can override the os with a homebrew to bypass logical security. if there is less that can be done with the specs them there is less motive for homebrewing. in the past the gba and ds were emulated, or ran on a computer quickly but their successor the 3ds still can't be emulated. that is because even the old ds emulates had problems with 3d games. because of good new technology the emulation of their handhelds has slowed. this goes for the psv that recently came out as the hacking emulating community can't understand how it works. maybe in the future there will be devices that only allow the viewing of the internet because of the low specs of the device to prevent peple from going on viewing video or playing games.
