How about this, what are his questions and concerns? I will try to answer them for you, I have run switch stacks for about six years. And I have had very little trouble with them. Imagine having eight separate switches, that need a separate management IP's, that need a separate configurations to be saved and backed up nightly, less redundant by nature in the case of a hardware failure as its easier to lag switch one and seven and get redundancy through the stack, then to have two uplinks per switch, creating more opex.
