With the advent of tablet computers etc it is becoming more common for players such as myself to keep an electronic copy of their character sheet, instead of or along with a paper copy.
Their is an editable Pathfinder sheet, but like the Wotc sheet, the data can only be entered once, then the sheet is permanently locked, thus making it great for presenting characters for one-shots, but almost useless for a player to maintain an electronic record of his character.
Might I suggest that Paizo produce an editable pdf character sheet that can be constantly adjusted and updated. Redbrick did so for their Earthdawn game. Following the revision of the game the sheet is no longer on their website but here it is from my Dropbox account to demonstrate.

Such a sheet for Pathfinder would be great!
