Two weeks ago I had a meeting with Microsoft in Stockholm and one of the cool gadgets that I got to bring with me was the Arc Touch Mouse that is going to be released in November. From my conversation with Microsoft I understood that it will be bundled with certain computers from different manufacturers.
It is a driver friendly mouse. I have tried it both in Windows 7 and Mac OS X laptops and have not had the need to install any drivers for it.
What I do like about this mouse is that the Blue track technology that it uses allows for using it on a lot of different surfaces. So far I have used it in coffee shops, trains and at the university and have not had issue with the mouse tracking my movement.
The first thing that they showed me was show do you turn it on? That question was surprisingly easy to answer. You turn it into a bow, and it is turned on. When you have done this you will see a small blue light under your mouse.
The problem that I have discovered so far with the mouse is that you attach the receiver at the bottom of the mouse when you flap it out, but the trouble is that I am afraid that I will lose it really easily, more than once I have put it in a separate compartment.
When you use the mouse you feel a small vibration in the mouse to give you feedback that you are using it on. Even though it is in beta I have found the mouse to work really well and the ’”feedback mode” works really well both in OSX and Windows.
One thing that I like to check on my mobile mouse’s is how is the battery life? So far I have discovered that is really great. Been using it straight for the last two weeks and so far I have not had to switch batteries in my Arc Touch Mouse. What I am complaining about is the receiver, it works really great but I would like to see that Microsoft made a Bluetooth compliant mouse so that you would not have had to carry that receiver with you each day..
Conclusion: It is a small and portable little mouse that allows for easy usage and works really well. When it is released in November it is a must have for any laptop owners out there.
From what I have been able to gather it will retail for 79.95 US Dollar and so far it seems worth it. If you compare it to the arc touch mouse the differences makes it a worthy upgrade.

Micael, as far as working on OS X is concerned: did scrolling work out of the box as well?
Never did unfortunately.
