Really?
Give it a month or two, the markets will settle down, sterling will strengthen again, people will exit gold, Europeans will reinvest in our economy and it'll be business as usual. I can't think of a single time that Gartner has been remotely right about anything, so I'm not inclined to start believing them now. Quite the opposite, in fact.
Postponing an order with a large FX exposure right now is thoroughly prudent. Cancelling all foreign expenditure for the next two years would be just plain stupid. Still, there is a high degree of stupidity to be had, mostly in the consulting industry.
