How is there a benefit at the 'current' exchange rate? If the price isn't set in GBP, what have you got to compare against, regardless of the rate right now?
If you were never in that situation, my experience is in paying less over time as both GBP/EUR have been getting stronger than USD.
Plus, pricing in the home currency is usually larger than the exchange rate (i.e. $10 = £5.83, so pricing would probably be something like $10, £6. Or even more - if not $10/£10 - you know who does that!...)
I'm working on the assumption that if they suddenly started offering services in GBP, they'd price at £5 rather than $5 (like virtually all companies do). Meaning the same service would end up costing £2/month more than it does atm with the current exchange rate.
