The I2C bus seems to me to be better in cases where there are a _large_ number of devices with smaller volumes of bus transactions, or if the devices can wait for a considerable amount of time before reporting back their data. Also, the I2C bus is a multi master bus, and I have a feeling you wont need to run accelerometers as bus masters :P
IIRC the history of I2C was that it was created in retaliation for Apple not freely licensing Apple Desktop Bus. I2C never caught on as a keyboard/mouse interface but is widely used for other things such as temperature sensors.
ADB has since faded into obscurity. When Apple started using USB on the original iMac, USB took off.
