A few technology devices I've started to use...
A SanDisk MobileMate SD+ Memory Card Reader. Works great for transferring photos from the Kodak EasyShare Z712IS camera, or rather the SanDisk 2GB SD card. The card and reader combo seems to go faster than the camera and USB cord. And it was the only way I could figure out how to upgrade the firmware for the camera.
BestBatt.com has replacement batteries for the Z712IS that work. I didn't have much luck with the Kodak brand rechargeable batteries Ni-MH AA batteries. So, I purchased 2 of the KLIC-8000 replacements. And a charger. Delivered in a timely manner for less than $50.
