Microsoft has announced a sweeping international expansion of Surface Pro availability. Until this point, Microsoft's top-tier Windows 8 tablet has only been for sale in the US, Canada, and China. But by the end of next month, that's going to change in a big way; Microsoft says Surface Pro will reach the UK, Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Luxembourg, New Zealand, the Netherlands, Norway, Portugal, Spain, Sweden, and Switzerland by the end of May. In June, the international tour will continue with availability planned in Russia, Korea, Malaysia, Singapore, and Thailand. The company's base Surface RT product has already seen much wider availability overseas, but Microsoft plans to add Korea and Thailand to that list by the time June wraps up.

Speaking to Surface Pro availability in North America, Microsoft says its had trouble keeping the 128GB model on shelves so far, but is confident that retailers and its own stores should now be adequately stocked.
