Will 3D be the next major TV trend?

This week’s question concerns 3D TV. The recent success of 3D movies such as Avatar has added to an already-growing interest in 3D television and content. TV makers such as Sony, Samsung Electronics, LG Electronics, and Panasonic showed 3D ready televisions at the recent Consumer Electronics Show and expect to begin shipping units later this year. But numerous obstacles remain, including high cost, standardization of 3D signal and interface formats, content availability, and the inconvenience of wearing special glasses to view programs. What do you think? Will 3D be the next major TV trend? Yes or no?

Can a global ban on producing nuclear weapons material be enforced?

This week’s question concerns nuclear weapons. Diplomats from 65 countries are meeting at the United Nations Conference on Disarmament in Geneva this week to discuss beginning talks on a possible treaty that would stop nations from producing plutonium and highly enriched uranium – key materials used in nuclear weapons. Proponents believe such a treaty would limit the ability of countries to manufacture and stockpile future nuclear weapons. Critics point to a number of issues, such as who should pay for inspections to ensure compliance, how to detect if countries are cheating or secretly producing material, and what should be done about existing stockpiles of nuclear fissure materials. What do you think? Can a global ban on producing nuclear weapons material be enforced? Yes or no?

Can tablet computers make greater inroads in the PC market?

This week’s question concerns tablet computers. Apple Computer is strongly rumored to soon unveil a tablet computer able to play music and video, read E-books, and provide Internet access. Several PC makers, including Motorola and Hewlett-Packard, also demonstrated tablet computers at the recent Consumer Electronics Show. While tablet computer proponents believe these devices can carve out a market niche, skeptics say tablet computers will have difficulty competing in a market crowded with netbooks and smartphones as well as laptops and PCs. What do you think? Can tablet computers make greater inroads in the PC market? Yes or no?
