More costly training.
Oh good, a whole new Cisco OS. I'm convinced their business model is based primarily around emptying the pockets of CCNA's and CCIE's.
Why else would the IOS be one of the most obtuse and awkward means of configuring equipment known to man?
Cisco kit is like a Lamborghini Murcielago with a drivers seat made from razor blades - all performance and zero useability. What other excuse can there be for equipment that *requires* configuration from a command-line in 2008? Accidentally wiped the IOS binary from the "capacious" 32MB of flash memory on your switch? Not a problem, just transfer it using XModem via a 9600bps serial connection - see you in 6 hours.....
