While Apple's iPad currently dominates the tablet market here in the United States, new gadgets debuted at the Computex Taipei trade show could prove worthy competitors.

For those still in doubt about the shelf life of tablets, look no further than the Computex event, where tablets appear to be the hot ticket technology. According to reports, several manufacturers have used the event to introduce new devices, many of which are cheaper, more powerful and flashier than the iPad.

One such device is the Ultrabook from Intel. Introduced by Intel executive vice president Sean Maloney, the Ultrabook is an ultra-thin laptop that includes many tablet-like features.

Taiwan-based AsusTek unveiled its own hybrid device – the Padfone, which combines the features of a tablet and smartphone. The 4.3-inch device is capable of making calls and connecting to the web and apps. It can also be plugged into a 10.1-inch tablet dock, which boasts a longer battery life, speakers and an I/O extender.

Despite the new players, industry analysts expect Apple to maintain its dominance for years to come. According to Gartner, Apple will enjoy more than 50 percent of the market until 2015.
