Before you shop for a tablet, consider your priorities. If price and portability are tops, consider the Samsung Galaxy Tab with Wi-Fi. If access to the largest selection of apps is high on your list, choose the iPad. Other factors to consider when buying a tablet include the availability of a 3G version, the existence of built-in ports, and the operating system.
If you need Internet on the go, consider a model with 4G connectivity, but be prepared to pay more and subscribe to cellular data service. If your needs are simple -- reading, email, web and online content -- consider one of the low-cost "specialty" models linked to Amazon or Barnes and Noble. Other factors to consider include the presence of built-in ports, a back-facing camera, GPS, and the availability of a keyboard dock.
