I was a big opponent of bitcoin- still wouldn't use it for anything that matters- but there are some great use cases.

Example exchanging 500 GBP to EUR (via intersango at current rates):
Buy 104.6 BTC @ 4.76GBP Fees for instant trade: 0.95% = ~1 BTC. Balance: 103.6BTC
Sell 103.6BTC @ 5.8EUR = 600.88 eur Fees for instant trade: 0.95% = ~5.71. Balance: 595.17EUR
500 GBP went to 595.17EUR. Exchange rate: 1.19. (google tells me the exchange rate is about 1.26 at the moment, so this is quite poor)
