300 dpi internet coming soon?
Daniel Jalkut has an excellent blog which describes a computing world where the user selects the resolution - no longer being bound to the 72 dpi world. Vector graphics are already found all over the Macintosh OS and Microsoft Vista, so why wouldn't the web also need to upgrade? To me, this is the real web 2.0 - a true world of blended vector and raster graphics. They could call it "RV" :-)
One thing is for sure, when the switch is made there will be a lot of bitmap designers scrambling to learn the nuances of Illustrator and other such vector based apps. Otherwise theire graphics will look miniature or chunky depending on the user's preference.
Here's another discussion of the balanced approach, or having a mixture of vector and bitmap.
And then how does SVG and VML play into all of this?
