The artical assumes 1080i to 1080p conversion is a lossless process. It is not always straightforward. 1080i from non-progressive sources has iterlacing which is clearly noticeable when directly converted to progressive by merging odd and even lines. It makes more sense to drop the odd or even lines when converting to 720p than bothering to de-interlace using some image processing techniques. Any de-interlacing technique softens the image and in my experience is worse of than reducing the vertical resolution by half.
Digital Cinema 1. Reduces cost of distribution significantly. Each film print costs to the order of few thousand dollars and is not reusable. Whereas, digital media can be re-used. 2. Eases distribution (can be distributed through satellite, DVDs, tapes, hard-disks etc) 3. Had consistent quality. The digital content is not prone to dirt, scratches etc. 4. Is Easy to manage big multiplexes with digital cinema. Has a lot of potential for automation. 5. Adds more functionality to a cinema. A digital cinema can be used for libe shows (sports - football, cricket), concerts, education, games.
Why digital cinema is bad? 1. The current digital projection technology is not advanced enough to beat analog projection. The DLP can go 1280x1024 only. JVC's DILA is yet to be in the market. 2. Film is a more mature technology. Reliable and stable. 3. Compression artifacts spoil the fun of watching movie.
Conclusion - Migration to digital cinema is inevitable. The only question is when?
...(Sending a gigabit of information per second is equivalent to transmitting the information content of approximately 1,000 novels every second; sending 40 gigabits per second over 64 channels is equivalent to transmitting the information content of 2,560,000 novels)...
Information measured in units of novels? Novel is text only data. So, 1000 novels doesn't sound impressive. 1 DVD per second would be more impressive:).

Because Microsoft will make it more user friendly for them to use.
IMHO command line tools are good but only for simple tools. Its not so straight forward to use zillions of command line options. The GUI makes it easier to navigate through the different possible options.
A combination of GUI and command lines is the best. For example, tools like imageMagick provide both options of GUI based manipulation and command line options. So, complex command line options doesn't scare away a newbie:)

so people will start saying ping instead of hello...that would be cool
