comment Historical Exchange Rates via FinancialData
The motivation of accessing this data comes from several recent hunches that the Australian dollar is significantly overvalued (anticipating a fall to ~80c by 2015 for future hunch-judgers) but don't particularly trust my intuition when it comes to predicting notorious currency movements - nor for that matter Australia's Reserve Bank or this country's economists. Whether big data-driven finance models can prove to be any less Sisyphean, Faustian or even King-Cnut-like is debatable but going there would at least appear inadvisable without access to such historical data.

The range of computational data available in Mathematica promises much but not making explicit current scope limitations is IMO unfortunate. Part of the power of the Wolfram Language lies in its generality and uniformity so it's a reasonable expectation that unless notified otherwise this will extend to data sources. Where it does not, either because curation is not yet possible or else subject to further licensing, making these explicit (perhaps graphically and/or through additional licensing instructions) would greatly assist users scoping out potential applications.

@Kuba brevity as per accepted answer in mathematica.stackexchange.com/questions/31152/… but yes on OS X the syntax coloring prior to evaluation indicates non-standard usage so yes "None" is probably better -otoh maybe a latent wish that without either (i.e. single argument) would syntactically suffice since the pattern shouldn't interfere with other option usages?

no syntax error on V9.0 on OS X. Does Grid[{{1, 2}, {3, 4}}, ItemStyle -> {None, None, {{1, 1} -> Directive[30]}}, Background -> {None,None, {{1, 1} -> Red}}, Frame -> All] go through?

Yes I similarly overlooked this point and it does seem to confirm that this significance level is being inherited from the original invocation.
