*WARNING: CAR ANALOGY*,/p>
I agree (somewhat). I use XP on a Duo Core HP at work and it is pretty responsive however I attribute that to the horsepower under the hood rather than how light the body is. You can make a '57 Cadillac run the quarter mile in 10 seconds but it doesn't mean it's the same weight as a Civic. I have used XP on older hardware (circa 2008) and it's touch and go at times. Pre-2005? Forget it.
Another point is the upgrading portion. We are in the process of migrating to a new MRP system and our old system is the one which has required us to use XP (or virtualize XP on the new Win7 machines). It eventually will happen that staying costs more than moving forward. My only thought is how long will it be until the OS doesn't matter?
Exactly. I don't know how many times my spreadsheets have kicked out something that I go 'There's No Way In Hell...' and I then went back and double and triple checked and found the error. If I didn't, I would get somebody else to look it over. If the numbers still stood up I would pass it along/up the chain with a note that I didn't believe the numbers were accurate. While this may not look great to the higher ups because they love hard numbers, they would much rather have your opinion that you think something is wrong.
tl;dr - Once you are done doing the math, ask yourself if this makes sense. If it doesn't - go figure out why.
