I realized something about the network her at work today. We have 1 full time tech guy, and the network hasn't gone down once. At my previous job, we had 5 full time tech guys, and the network went down regularly. I can't help but think that PC networks (with PC workstations) require more people to be less stable with more downtime.
One of the common arguments I hear about PCs is that they are cheaper than Macs. Lets assume a PC is $200 cheaper than a Mac. Now, some will argue that a $999 PC isn't really equal to a 1199 iMac, but that's not something we'll deal with. Lets just say $200.
We'll assume each network has 25 computers, and 25 users making $15/hour and that the tech team makes $20/hour per full time employee. For the PC network we will assume 4 hours of downtime per month which, from my experience, is pretty accurate.
5 Full time tech support = - $208,000 per year
PCs at $200 less than Mac = + $5,000 one time cost
25 user downtime for 2 hours = - $18,000.00 per year
One year of operation, assuming no replacement parts on the computers would cost:
($208,000) + ($18,000) - 5000 = $221,000
Now, for the Mac.
1 Full time tech support = $41,600
Cost saving = $0.00
25 user downtime for 0 hours = $0.00
So, the cost of 1 year of operation is $41,600.
So it looks like a PC network costs you $ 179,400 when you add in the cost of employees and downtime impacting the rest of the staff. But hey...at least you saved $200 on all those nice new machines.
