Tablet appeal bolstered by security, cost effectiveness

Going into 2012, the tablet computer will build on its success of the last couple years, causing a greater disruption in the PC market and stealing away sales that would otherwise go to more traditional systems, according to Jack Wallen of technology news provider ZDNet.

Security is one element that's drawing people toward the tablet, Wallen writes. The mobile devices, he says, are not as vulnerable to viruses and malware as PCs, though tablet-specific antivirus software can still be found.

Cost effectiveness is another big part of the tablet's success. Though prices vary, the near-standard $500 mark seems to be one that many people can get behind, as it is comparable to a low- to mid-range laptop. Tablet computers may sacrifice some of the functionality of laptops, but they make up for it in portability and an undeniable "in" reputation at the moment.

Laptop sales have slowed in recent years -- partially due to the tablet and partially due to the overall economy. According to research firm Forrester, tablet sales will eclipse laptop sales by 2015.
