— People generally have much less experience of utilizing their mobile to travel online than they do of using their computer. This means that computer-based users can be assumed to possess a higher level of existing expertise than mobile and handheld misje.dev.mbnet.pl users.

Computer-based guests generally only differ from each other in their web browser and operating-system (i. electronic. most people will make use of a screen, mouse button and keyboard), whereas the different types of mobile phones and PDAs are different can greatly.

Which mobile phones and PDAs must you consider?

Mobile phone devices and PDAs can differ from a another greatly, and this can radically adjust how people experience and use websites. Some of the ways handheld products can differ consist of:
