I know that some DMs don't like to use a laptop at the table, but I find it invaluable with 4E since there are so many things to track in combat. Here is a youtube vid I made highlighting my workflow with some of the tools I use at the gaming table: https://youtu.be/ZH24-Fdo8E8. Not really helpful if you do Roll20 or a related tool for remote gaming, but very helpful for in-person games.

Some Digital Tools (most are shown in the video):
  • Character Builder
  • D&D 4E Combat Manager - this is open source, which is super awesome.
  • Offline Compendium - requires DDI to take advantage of this.
  • Power Card Manager - tool I created for tracking powers for each character and their usage state. Players can bring it up on their phone and changes sync with 4E Combat Manager that DM is using.
