Contact management is decent in so much as Facebook, Twitter and Google accounts can all be added in quick time and linked together into single profiles. The process of linking contacts is a bit laborious but with a bit of patience you soon get there and from then on in the contacts interface is very nice to use. The lack of smart-entry (shows matching contacts as you dial) when using the dialler is a bit of an annoyance, though.
Another plus for Android 2.3 is native VOIP support – you can now just add in your account details to a contact and it will treat it just like a standard phone service. Currently, however, it doesn't support Skype, which is a bit ridiculous.
Standard video calling is supported and it works as well as any other standard video calling service, so trumps Apple's FaceTime for the fact it can work anywhere but is generally quite poor quality over the 3G network.
Call quality is reasonable for both caller and receiver, though the speaker phone isn't amazing. We really do wish these Android smartphone manufacturers would learn a few lessons from Nokia and RIM, who still hold the crown on this front.
We've already mentioned how good the keyboard is but in many other ways the messaging abilities of the Nexus S are also superb.
SMS messages are nested into conversations so you don't have to trawl back and forth to find previous messages from any one contact. Email is also excellent with all the usual account types catered for and neatly presented, with setup being a breeze. As ever, Hotmail users will have to make do with POP3 connectivity as Microsoft rescricts access to its email service for every platform but Windows Phone.
This phone's web browser is excellent providing very rapid access to properly rendered web pages with full support for Adobe Flash. As mentioned earlier, things can grind to a halt when viewing demanding Flash content but with you able to set Flash to load only on demand, most every day browsing is unaffected and of course it's a big boon over the iPhone and a number of other phones out there.
Text reflow is available to ensure all the text on a page fits to the width of the screen, no matter how much you zoom in. It is a little bit temperamental in terms of when it wants to resize or not, though. Thankfully the act of zooming is nice and easy with both multi-touch zooming or a simple one-finger tap on the '+' and '-' symbols getting you there.
