I am planning on buying my first iMac in a few weeks. I was looking at buying the Apple Battery Charger so that I could have rechargeable batteries for my keyboard/mouse. My questions are: 1) What is the quality of the Apple charger/batteries? Are they my best option for use in these Apple products? If not, what would you recommend for a similar (or cheaper) price? 2) I believe the charger comes 6 batteries. I am thinking of getting both the Magic Trackpad and Magic Mouse. Combines with the wireless keyboard, this would require 6 batteries in use at all times (with no spares waiting in the charger). For others with all three wireless devices, do you use a different brand of charger/batteries that allow for 8+ batteries? Is there a way to buy extra batteries from Apple that anyone knows of?
