Microsoft on Tuesday announced it is expanding the availability of its Surface RT device to 29 markets and the Surface Pro to 27 markets. All the launches will be taking place over the next two months, meaning by summer a significantly larger number of consumers will be able to buy the company’s computers.

Currently, the Surface RT is available in Australia, Austria, Belgium, Canada, China, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Japan, Luxembourg, the Netherlands, New Zealand, Norway, Portugal, Russia, Singapore, Spain, Sweden, Switzerland, the United Kingdom, and the US.

Microsoft plans to bring the Surface RT to Malaysia on April 25, to Mexico by the end of May, as well as to Korea and Thailand in June. The company wouldn’t reveal specific dates for the last three markets.

The Surface Pro meanwhile is currently available in just three countries: the US, Canada, and China. Microsoft thus hopes to increase that number nine-fold for its higher-end device.

Microsoft plans to bring the Surface Pro to Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Luxembourg, New Zealand, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the UK “before the end of May.” It will launch in Korea, Malaysia, Russia, Singapore, and Thailand “before the end of June.”

Last but not least, Microsoft admitted that one of its “biggest challenges” has been keeping the 128GB Surface Pro in stock. The company has been working hard to increase availability, and is now confidently saying that “most retail partners” in the US and Canada as well as the Microsoft Store now have the 128GB flavor “consistently in stock.”

Whether Microsoft will be able to keep this promise in other markets remains to be seen. The 128GB flavor is sought after so much because the device is being advertised as more than just a tablet: if it can be used for work and play, consumers want as much space as possible to store all their productivity programs as well as their personal files.
