Only just found this post so sorry for the delay in replying.
I was actually lucky enough to trial this pump earlier in the year, but then it was known as the Asante Pearl, I've only just discovered the name's been changed.
The following article gives quite a good overview of what the pump offers, if not try their website -

I have to say it suited me very well because although there's no separate user interface like the Accu-chek Spirit Combo, all the information you need is on-board. I personally find the time lag when trying to connect the Spirit to the hand held is a real pain in the a**. One thing that I particularly like with the Asante pump is that because you manually enter your BG reading your not limited to a measly few minutes leeway to program in a bolus. I don't find this much help if I check my BG as I'm preparing a meal for the family but don't necessarily want to bolus just yet. So the Asante is a lot better in that way.
I've also had a lot of problems with the Spirit in that it never seems to give me an accurate reading of on-board insulin. The Asante seemed brilliant in that respect.
Downsides - well, I personally had a few problems with air bubbles in the Asante although none of the others trialling it with me did, so maybe that's just operator error! Also at the moment its only licensed for use with Humalog cartridges (I use Apidra), so not brilliant but for me it would be a reasonable trade off.
I spoke to one of the marketing team at the end of the trial and at that point they were hoping to release it in Europe some time next year - that would probably be places like Germany and France as they have a much higher percentage of Type 1's on pumps there. So I don't know when we'd be likely to see it, maybe the end of next year?
It won't suit everyone I know, if only because a lot of people do like the idea of a separate hand held/meter/whatever, but I was very impressed with it. Lets hope they don't take too long releasing it over here!!
