I also tried connecting from the X61t side, and it says
"The pairing attept resulted in an unknown error. The reported error code is 0x80070057

I graphed my battery life against hours of time used:
You can see that on day 1 the battery was losing 8.6 % per hour, but on day 3 the battery loss had improved to 3.5 % per hour. What did I change? Well I logged myself out of gchat, gps is off, and I changed gmail to push instead of check every 5 minutes.
