I love the idea of getting back to one-page character sheets. This could mean single-sided or double-sided, with the provision that a double-sided sheet doesn't mean two sides of densely-packed lists and numbers.
I came across this one-sided character sheet for a Labyrinth Lord game (B/X D&D retro-clone) a few days ago:

In looking for similar character sheets, I found these AD&D character sheets done by Tony DiTerlizzi:

Some will dislike these sheets because they have too much "wasted" white space and because there are too many "useless" visual touches.
I love these sheets (especially the DiTerlizzi ones). They're clean and uncluttered but are nice to look at and it's easy to find information on them.
I don't like the mass of boxes, lines, checkboxes, and lists of things on the official 3e and 4e character sheets. They end up looking like income tax forms, not my "user interface" to a fantasy RPG.
The in-play character sheet doesn't need all of the "workspace" fields provided on most of the 3e and 4e character sheets. You could have nicely presented sheets that have all of the calculated values, and then additional worksheets that can be put aside until characters level up. Even better, make the core game streamlined enough that you don't
need these kind of calculations. 3e really went out of its way to ensure that you couldn't just track your total skill modifier (skill ranks as pre-requisites, cross-class skills meaning that the order in which you took class levels made a difference, synergies, etc).
I'm going to make a custom sheet for my wife's 3.5 ranger, inspired by the DiTerlizzi ones. Unfortunately, I can't draw, so I'll be borrowing a lot of images. She'll definitely appreciate this approach over the typical 3.5/4e character sheet design.
