Remember, we all have different body chemistry, and deal with our disease in a unique way. If you are able to manage your BG levels with carb counting and MDIs, I personally see no reason to go pump. All the pump manufacturers have preliminary agreements with Dexcom right now, but it will be quite some time until this is available (I actually have my money on the Animas Ping getting the FDA blessing first).
That being said, even with integrating the two technologies, rember this is not a closed-loop logic system. In other words, the pump CGM integration is just a alternative delivery system for your insulin and in no way an "artificial pancreas." Still have to count carbs and "input" your bolus. I prefer inputing my bolus requirements by pricking myself with a needle instead of inputing a number on a computer. At least with my MDIs, the prick is ten seconds insted of being hooked up 24/7.
Cheers, and would love to hear how management develops,
