Guess maybe it depends on who's paying.
I agree with link, a new machine will be an upgrade across the board and will likely work much easier with less time spent f*king with it.
If it is a business machine, and you have other tasks besides tinkering with it, then it makes better sense to replace the machine with new, totally functional equipment.
Of course, the old machine could be reallocated and an upgrade could make that machine more of a benefit to the company with just a little of your time (learning along the way), Best of both worlds. I've used this excuse in the past...
and.... a machine that does scheduling isn't where I would decide to expand my computer knowledge....
