"Thus, when you see a 130W desktop-class Core i7 (Bloomfield) CPU shoehorned into a laptop, you don’t expect much in the way of battery life (to be fair, Thomas got nearly an hour out of Eurocom’s D900F). That’s like trying to get a V8 under the hood of a Prius—totally defeats the point, even if there is a small contingent of folks who can actually put that self-contained horsepower to use."

It had to happen eventually.  While there are companies who are more than willing to stuff a desktop CPU into a laptop sized casing, Intel has finally made a Core i7 CPU designed specifically for the mobile market.  As with most high-end, eats Prime95 for breakfast, processors, the resulting laptops tend to be more transportable, then mobile.  Tom's Hardware got their hands on a Eurocom Cougar, which features the Core i7-920XM and predictably, the 920XM does best the Core 2 Extreme QX9300 it is being compared to.  Still, if one can hold out for just a few more months, Tom's notes that the next generation, Arrandale, should provide comparable oomph with much better mobility.  Having a 17" behemoth myself, I can honestly see that Arrandale will be the CPU to keep an eye out for.  Anyone waiting for a laptop to sport this powerhouse, or does mobility win out in your mobile choices?

What I'd like to see is the bottom rung i7 mobile benchmarked. I think it's the i7 720QM.

Also, I'd like to see how it performs to some desktop processors, like the new i5 and i7s. Some of us still have desktops and would like to see how much we lose if we switch to a notebook for work.

While hardly comprehensive, there is an entry for the Core i7 720 from Passmark:

To be honest, from a pure performance point of view, it doesn't look too bad though it seems to even lag behind Core i5s a fair bit.
