Mobile Online Poker?

Hey, I was just curious and thought I should ask whether there are players who download and play online poker right on their cell phones. I know a couple of sites have the capability including Party and PokerRoom. I was just flipping through the site and I see the ad to download the PokerRoom software onto a mobile phone and made me wonder: Are there people who do this?

As much as I love the game of poker and would like to play it more often, but wouldn't that take someone out of the atmosphere and mindset, even if it's in the comforts of one's own home? It is a good idea, if someone wants to play while on the go, but wouldn't that be more for fun as opposed to playing for more serious stakes?

Just thought I would get some feedback or various opinions on this, as it seems like an interesting niche market, but gauging if it is actually sticking for players.
