My new FastMac battery for my 3G iPod (a TruePower battery) arrived here today. It was on campus yesterday afternoon, but just missed the on-campus delivery truck. That's amazingly fast delivery from California to Calgary, even adding some time for the package to be opened/searched by Customs at the border.
I'll try upgrading my iPod's battery tonight, and will take pics of the process to show what it looks like when a total hardware upgrade amateur tackles it (I've upgraded RAM and hard drives in Powerbooks, but that's about it...)
They also threw in a car iPod charger, and a portable charger. I'll definitely be putting both to good use, and will write up mini-reviews when I get a chance.
