Well, until my work dried up, I reflashed BIOS's on a regular basis,mainly due to clients "trying it for themselves" and royally mucking itup, like flashing the BIOS with the power of the UPS only, or restarting because the machine locked and so on. As for flashing them in general - only when needed for example the 32gig harddrive issue - I used to get this alot as most of my clients didn't want to upgrade the whole machine because theywanted the extra space.
