Today, Jonathan Snook posted about CSS Matrix Layouts, a proposal for a third way for creating advanced layouts in CSS3, with Advanced Layouts and Grid Layouts being the others. His ideas are around creating a grid and defining sections (be it divs or natural HTML5 elements) that are effectively laid out like a table. Each section can span like a table can span rows and columns, with all those values being stored in CSS. Take a look at the post for an example, it's quite simple once you get your head around it.
A colleague of mine and I were discussing the current state of the internet, CSS3 and IE being behind the rest of the browsers in terms of standards adoption. He argued that IE was "rubbish because it doesn't support CSS3 selectors/borders etc". My reply to this was, "well, do something about it".
iPhone development is the forefront of "cool" programming. Doing something with your latest toy and potentially selling it to millions of people, making a few bucks along the way. The main stumbling block (assuming you have a Mac) is the Objective-C language.
