iplay4e.com has a tablet-specific view of your character data.
It's free.
It has shortcuts to DDI Compendium entries, for when you need to look up specific rules on an ability.
Export your character from the character generator and import it into iplay4e.
Security goes through Google Accounts, so no new login.
And you can track current status, like hit points, surges, encounters and dailies used, etc.
They also have a phone-size-optimized view of your character, and it works great on an iPhone.
