Another rocket, Ares V, would have the capability to launch heavy payloads - service and cargo modules - that would be needed to service Moon missions.
Meanwhile, wind and building-integrated solar modules with high efficiency photovoltaic materials can supplement our electrical generation capability, as stricter building codes and improved insulation can decrease the energy used to heat and cool buildings.
Developers can also break apart some applications, like Gmail, to easily change look and layout on different tablets (think of it as a marriage of programming in modules and graphic templates.) There is a good 3-D capability, so scrolling YouTube galleries, looking at album art or turning the pages of ebooks looks good.
