Tablet devices such as the iPad and devices running Android operating systems are becoming increasingly popular. They are lightweight, portable devices with touch screens that are designed for activities like internet access, email, reading ebooks, and watching multimedia content. While tablets provide advantages like long battery life and ease of use, there are some limitations to using them for tasks like typing or accessing Flash content. Different tablets may be better suited for different users and purposes, such as the iPad being well-suited for casual home use while devices like the Samsung Galaxy Tab can offer more features for mobile professionals.
