In an attempt to get some of its mojo back, the PC marketplace is going hybrid, or convertible, depending on who the manufacturer is. Revealed at the Computex show in Taiwan earlier this year, the “two-in-one” is the industry’s answer to consumers who are having a hard time deciding on whether or not to buy a tablet or a new laptop. Since people who use tablets are likely to hold onto their laptops longer before upgrading, the industry is seeking to spark demand. A laptop-tablet hybrid, the two-in-one models have screens that either detach or fold back so they can transform from laptops into tablets, giving users the best of both worlds. Many experts predict the devices will be hot holiday gifts this shopping season, but they could also be hits with business users who need more than a tablet can provide.
