Most of the mobile phones today come with some sort of a web browser. Opera Mini
is the most popular browser but there are many more. Different browsers support
different features, and break some! Testing across browsers is one of the biggest
challenges in mobile web development. The situation is much worse than desktop
browsers, and we will see more on this in the coming chapters. The connectivity to
the Web depends on the carrier you are on. You may be on GPRS, 3G, Bluetooth,
WiFi, or anything in between.
PDAs
Another class of mobile devices is PDAs. Personal Digital Assistants have been
around for quite some time and have evolved over this period. They contain
many business and productivity applications??”email, office productivity, and
custom-built software. Typically, they have a QWERTY keyboard??”either in the
device or onscreen. Phone functionality is an add-on for PDAs, and most consumer
PDAs are smart phones now. These handheld devices are merging with phones now,
and are very popular with business users.
