As CPUs get faster an interrupt costs you more in terms of lost CPU time. So, reducing the number of interrupts is more important now than ever before.
My 100 Mbs ethernet card generates about 5k interrupts / second when transferring data at about 30 Mbps. Gigabit cards are engineered to hold interrupts until a few packets of data come in so that a DMA can move a larger chunks of data. If this NIC reduces the use of interrupts even further (say by off boarding computation or even the entire TCP/IP stack and thus allows for even larger DMA transfers) the impact could be substantial.
Unfortunetly, my knowledge of computer innards stops here, so I can't calculate how much cpu time 5000 interrupts actually take or how the new PCI-Express bus changes interrupt processing or how much a benefit it would be to have say only 1000 interrupts / second instead of the 5000.
The truth of the matter is that e-machines acquired gateway - and got PAID to do so. Don't believe me? Here's the story - pieced together from articles from PR from the last couple of months.
About 12 months ago Gateway Founder and CEO Ted Waitt ran into a man named Wayne Inouye, CEO of e-machines at a trade show. At the time GTW was trading at $3.50 - below cash value of the company. Inouye was interested in doing a leveraged buy out. The combined force of e-machines (4th largest computer manufacturer at the time) and Gateway (3rd largest) would have made a powerful combo. But for whatever reasons the stars did not align. Fast forward 12 months later. Gateway announces that it will "purchase" e-machines for $235MM in cash and stock. Inouye was named CEO and Ted became chairman of the board of the new company. Last Friday is when the axes fell...Of the 17 people reporting to the Waitt, 15 were out right fired and replaced with e-machines leadership. The remaining three (including the CFO) were demoted in title.
In my opinion there is more to come -- you see e-Machines is a 138 person company with revenue of (get this) $1.1 Billion. The 7000 people at gateway pull in under 3 Billion. I don't have a business degree or nothin' but it sounds like e-machines is a much leaner meaner company, which - given the new leadership structure - is exactly what gateway will become.

From what I remember, 70mm file has roughly 4000 rows or resolution... so, I'm not sure why people would be so astounded by the resolution of this UHDV system. Perhaps the impressive part is really the frame rate?
Despite what it may feel like, pop-up ads account for less than 5% of the total advertisements on todays websites. Further, AOL (see this NYT article posted on./ several weeks ago) has confirmed that pop-ups are a huge source of dissatisfaction from web users - thus making them in-effective.
Rather than use "anti-leech" technology, wouldn't advertisers be better served by simply employing technology that would be more palatable to their readers?

Summary is that TimeWarner says that TWX and MSFT have been talking about DRM, but that the other rumors are simply not true. The full press release is here:_ 2.html
