Samsung may make some good phones but to link to the PC then you have to use Kies and that is poor. You can have endless problems syncing contacts and calendar with Outlook. It's ok if you use Google mail contacts and Google calendar but exchanging data between Outlook and Google can be awkward especially now Google Calendar Sync has been withdrawn. By comparison the iPhone works seamlessly with Outlook and has a great array of apps with little risk of virus or malware. It also seems better built.
Phone reviews never compare ease of PC sync.
