Re: Impressed?
I am not surprised one bit.
Rather a lot of companies either don't want to go to the hassle and expense of keeping products under support, or can't be arsed to plan the downtime to update the software, or the failsafe excuse of "well, it's working fine, why should be update the firmware on it?"
We had a few devices that we didn't want to update, because they had a very specific and fiddly configuration on them that would break if we updated the firmware. (We also ran into firmware updates breaking actual OEM purchased switch port blades because the blade revision wasn't compatible with the newer microkernel, AND we couldn't run two different revs of the board in the same chassis.)
Fortunately, we ended up replacing them outright with newer units entirely.
