All meters should come with dose wizards like the Expert. The dose wizards should be expanded to include extra parameters like fat and protein as well as carbs. Meters should integrate with wireless-enabled pens to support IOB tracking like pumps do, and factor IOB into their dose wizards.
Privacy concerns with wireless meters and pumps need to be addressed. This can be done by applying well known principles but will only happen if security experts are involved instead of having security designed by amateurs as has happened up to now.
Meters (and pumps) should suggest possible changes to carb ratios, correction ratios and basal rates, based on observed readings and known inputs over a period of time.
Meters should have a "basal test" mode that alarms every hour or two and calculates the rise or fall rate and a suggested basal rate change based on the ISF stored in the meter.
Similarly you could have an ISF test mode and a carb ratio test mode. These could also be used to confirm the insulin action curve for IOB purposes, and store it on the meter.
A meter with all this valuable information on board would need the ability to restore this information from a backup if the meter was lost, or lost memory, or to clone that information to another meter.
