That "standard" 4e character sheet looks like a tax form, and any time I've given it to new players, they've found it confusing. The power cards also have a terrible layout, so I hope those are dramatically improved as well.
I managed to squeeze much of the "crunch" onto a single landscape page + power cards; I don't need a space on my character sheet to record mannerisms, appearance, etc.; I can save that stuff in a text file (or Evernote, or Obsidian Portal wiki page, etc.)
One of the tricks with power cards is accounting for all of the options: martial powers can change based on the weapon being wielded, implement powers can change based on the implement equipped, etc.
