Redmond and notebook batteries

I'll be in Redmond next week. As each flight to SEA-TAC is a long one, and the time I spend in planes is good for coding because noone interrupts me, and most of the times I get an upgrade to Business Class in United the seat does not have a notebook plug, I bought a Valence N-Charge battery.

It lasts 10 hours if you don't try to install the Longorn SDK from your DVD drive in a Virtual PC VM, in which case it lasts about 5 hours ;).
