That does look very cool! You're right though, it's not available on the NHS (yet).
Would be nice to see the Onmipod and the Animas Ping on the NHS.
I've got the Animas 2020, i've seen the accu-chek spirit close up. I prefer the Animas 2020, the screen and menu system seems much easier to use on the Animas, it's also a smaller than the accu-chek and not such a bulking thing when it's clipped to your belt.
I've not seen a minimed paradigm pump, so maybe someone else will give you an opinion on those. When i was researching which pump i wanted, it came down to the Animas 2020 or the Deltec Cozmo for features and look&feel.
Cheers
