I just watched a Poker SnG video ,where the "commentator" was using some pot odds calculator that he 'attached' into the interface or something. My first thoughts was that this was unfair, I do all the pot odds calculations in my head and thus I am not going to be that accurate. But I couldn't see how it can be illegal, the guy wasn't cheating per se. The calculator was just giving pot odds and odds-to-win etc.
Do lots of serious online players use this? Or is this frowned upon amongst regular players?
After watching the guy play following 'Calculateem Pro' it didn't seem like it was that beneficial; any decent player who knows basic poker theorem should be able to play just as well without it.
On a side note, in case anyone knows of the video i'm talking about, the guy in the video was awful, he was just all-in or fold pre-flop.

Edit: Ah I just saw the same program and a similar one on the FTR pokertools webpage. Stupid me. I guess my other question about how many people use it and how does the online community think about this is still relevant.
