I just traded my old Axim X5 for a Palm Lifedrive. For those unfamiliar, it contains a 4gb microdrive. I also have an 8gb microdrive, which is currently anything but useful to me because it's locked in TrueIDE mode (OEM mode). Would it be feasable to take the LD's MD out and replace it with the 8gb MD? would this for any reason decrease battery life?
