I use the Accuchek Mobile, and love it. It is compact and keeps everything together. I only use it for calibrations now, but used to download the data as all the BG data is in a .csv file hidden in one of the folders which you can find once you connect it by USB. With regards to the dexcom data, I was using Dexcom Studio, which is simply outstanding, however am edging more towards the Diasend s/w, simply because it is shared with my clinic online and allows my DSN to review and feedback at will, and integrates the CGM, pump and carb data (assuming you use the azCarb/ezBG function for bolus, which I do). I am about to buy a fitbit also, as I believe you can upload that information into diasend and whilst I am possibly the worlds unfittest person, with a severe allergic reaction to exercise (shortness of breath, turn red and sweat profusely at the mere thought of it ... lol), I am an absolute sucker for technology and more so data!
I should also point out the ezCarb and ezBG functionality is absolutely amazing and I don't know if other pumps offer it, if not, I would personally say its a reason alone for getting the Vibe.
