Iwas tempted to purchase the Bosch variation but was put off by the very short battery life reported by just about every review that I read. I hope that Milwaukee has done a better job. If I hear good reports, I will probably purchase one.
Milwaukee has a newer version of their 12v batteries that they are putting in their tools called red lithium. It's suppose to give the tool (drill, multi tool, etc. ) more power, better run time, etc. The multi tool is in the stores now, I saw one at home depot the other day and they have the newer battery. Milwaukee also has a high capacity battery that will get you much more battery life.

The cordless multi tools have a good use for cutting shims, cutting baseboard or other things here and there. Where you really see the battery life being an issue is for sanding or scaping, etc. The battery drains quickly with the continuous use.
In regards to the bosch corded version not yet released. One of the best contributors on the JLC boards was given one to write up a review. He said it was a very good tool and had more power than the Fein. He liked it a lot. He said the release on that in the US (I imagine CAN too.) will probably be within the next month or two.
