Currency fluctuations can be good for your business, ask IBM
Here's an interesting snippet of information: IBM's second quarter revenues were positively affected by currency fluctuations to the tune of 7% or around $1.6bn.
To put that in perspective, the $1.6bn from positive currency movements is equivalent to around 34% of hardware sales for the quarter, just over a quarter of software revenues or a tenth of services revenue.
You wouldn't get that good a deal at the bureau de change at Heathrow Airport.
