Everything Old is New Again
I was fortunate enough to have one the exploding batteries in my laptop (in its pre-exploded state) and I get a brand new battery. Huzzah!
Based on my previous one, I will go back to having a 5 hour battery life. Currently I'm only getting about 20-30 minutes on my old battery.
With a free upgrade to Tiger, new power cord, new motherboard, 1 GB upgrade of RAM, and a new battery my iBook should be good for quite some time.
