Now finally my original X201 battery (which is the only piece of hardware carried over from my old device) is starting to show its age. I'll get it re-celled soon with 3400mAh Samsung or Sanyo cells for a 113Wh battery (original was 96Wh, it's now at 65Wh at 66% capacity left).

Even at 65Wh left, it gives me more than an afternoon of mobility working on stuff via SSH and Waypipe plus browsing for info.
