Overall, I'd prefer CPC over CPM.
I just checked my stats and basing from what i saw, i dont see many advertisers have drawned into CPM. At least not for now, and this is my rationale.

As Big John used to say at the end of the Big John and Sparky radio show, "You go to your church and I'll go to mine, and we'll all walk along together."
an advertiser will always end up doing math do determinee return on investment. if they make $50 selling a widget, they know how much they are willing to spend on advertising in order to make a profit. CPC or CPM makes no difference. Google is going to show the ad that makes them (and the publisher) the most money. its all the same. just more math.
I'll bet that the CPM advertisers you'll see will be the ones you'd usually see on TV.... Coke, Pizza Hut, Motorola et al, where the success of the campaign is more to do with the amount of exposure in the marketplace, and not the amount of clickthroughs. Companies such as these pay hundreds of millions per year just to get their name out there in front of the audience. It will be no different to the CPM model.
By being able to select specific sites to advertise on, the exposure (at a low cost) using the CPM model could actually be a lot more profitable to advertisers, and a fairly attractive prospect.
In terms of publisher revenue, I hope it will encourage advertisers to go for quality sites, rather than some of the crap that's out there.
Makes an interesting prospect for publishers - marketing appeal could in the long term seriously impact earnings, where overnight "optimised" sites with little actual value to the user could see their revenue drop.
Could be an interesting set of data for Google to analyse as well - advertiser's choice could be a fairly influential indicator of quality and relevance in the long run! ;) Hello there Mr TrustRank! :)

I don't think AdSense CPM ads are aimed at the big mass-market advertisers, except for niche applications. Coke doesn't need AdSense to reach consumers; it can just as easily buy umpteen millions of ad impressions on the major portals and news/entertainment sites. On the other hand, there might be some value in site-targeted Coke ads if, for example, Coke wants to reach special-interest audiences--e.g., school PTAs that might be interested in fundraising with vending machines or collectors of Coke-branded clothing items.
A better example of a big company that might use AdSense would be 3M or GE, either of which has scores or hundreds of divisions, departments, projects, etc. that advertise in a plethora of trade and consumer publications. Scotch Magic Transparent Tape might not be a great candidate for AdSense "site-targeted" CPM ads, but 3M's sanding system for bowling alleys might be.
