The iPad comes with several applications, including Safari, Mail, Photos, Video, YouTube, iPod, iTunes, App Store, iBooks, Maps, Notes, Calendar, and Contacts. Several are improved versions of applications developed for the iPhone or Mac.
The iPad syncs with iTunes on a Mac or Windows PC. Apple ported its iWork suite from the Mac to the iPad, and sells pared down versions of Pages, Numbers, and Keynote apps in the App Store. Although the iPad is not designed to replace a mobile phone, a user can use a wired headset or the built-in speaker and microphone and place phone calls over Wi-Fi or 3G using a VoIP application. As of June, 2011, there were about 90,000 iPad specific apps on the App Store. The iPad cannot run the Xcode development suite since it uses iOS.
