Students’thoughtsabouttheimportanceandcostsoftheirmobiledevices’featuresandservices 

TelematicsandInformatics

Inrecentyears,handhelddeviceshavebecomeoneofthefastestgrowingcommunicationgadgets.Mobiletechnologyisbecomingwidespreadandresearchinthisareaisurgentlyneeded.Usingasurveyinstrument,thethoughtsofmaleandfemalestudentsregardingtheimportanceandcostsofmobiledeviceswereinvestigated.Itwasfoundthatstudentstendtoconsiderthefollowingfeaturesimportant:

batterylife,mp3player,videocamera,photocamera,storagememory,Bluetooth,designandelegance,clock,calendar,organizerandreminder.Also,theyareeagertospendanamountofmoneysoastheirmobiledevicetosupportthem.Onaverage,bothgenderswouldpayextramoneyforsuchfeatures.However,themajorityoffemalesthinklessofthepricethanmalesdo.Onthecontrary,mostoftherespondentsdonotconsiderthefollowingimportant:
