I personally think the mobile market has not worked out allot of technical stuff yet. At least related to Poker on the mobile. Maybe its much easier when it comes to casino type games which I have yet to try. I rank decent for mobile terms when it comes to poker and I can certainly tell you the revenue is nothing to jump for joy about 
I can give you a small sample size only because I only started to work with mobile for the last 30 days – maybe 40 days…

Deposits 19
GROSS RAKE = 51.08 Euro!!! – 20% of that is 10.22!!!!!
Month of work to rank and it appears 19 deposits is great but look at the amount on average per player.. LOL
50 cents per player is the value I get.
I do not mind cause I know its still in its infancy stages but I feel it will takes a few years still for it to ever even remotely come close to regular downloads and playing on computer for players.
And this is from ranking on 1st page of google!! LOL
