One should be banned though...
This is my reasoning. It's simple, and it's sound.
To start. I'm not knocking the incredible tool which these devices are. In fact, their very abilities are the cornerstone of my argument.
A person should only be allowed to play with the tools and abilities he/she can garner within themselves without any outside influence. Why? Because that's the way the odds
are set. (simple). To add outside influence unfairly changes the odds. (sound)
But what about the guy with photographic memory? They should be rooted out and banned from poker. Just like in Black Jack. These people have the ability to change the odds
. Not good. In Black Jack it's only bad news for the casino. They pay quite a lot of money to root out these geniuses. Changing the odds, changes everything.
In Poker, it's bad news only to us, while having no consequence to the casino. They still get their fee's and drops. This leaves it up to us. And since we have no casino/rules backing in these issues, it's allowed to infiltrate our environment at will. If it changed one little thing for the casino's... BAM
We should always be aware of the odds and more aware of any attempt to change them. We should not be allowed ANY outside influence into our betting process.
Bottom line... it changes the odds. And therefore should be out and out banned.
