They ignore the fact that they only use it to check email and surf the web. In that case, spending a lot of money to upgrade the processor makes no sense at all because you don't need very much power to do that.
Everybody needs money. If you need the speed more than you need the money then go for it. If you need the money but opt for the speed "just because" then you have bigger problems than a slow computer.
