Our Sony Ericsson XPERIA X10 mini came with no preinstalled document viewer so we had to snatch one off the Android Market. There is plenty of choice there so we don’t consider it too much of a disadvantage.
When you download an app it automatically integrates with the Gmail app as well, so you can view attachments. Unfortunately, you can’t save them in the phone memory (that only works for images). Attaching saved files (and we mean all kind of files) is possible though.
The other disadvantage is we didn’t find a free app that also supports editing so if you decide to edit documents on the X10 mini (highly unlikely anyway) you will have to spend some.
The calendar has only two view modes - daily and monthly. Adding a new event is quick and easy, and you can also set an alarm to act as a reminder.
There is also a calculator, a timer and a stopwatch aboard. Those are all nicely touch optimized - the buttons are big enough and easy to hit.
The XPERIA X10 mini features a decent alarm clock application, which allows a huge number of alarms to be set, each with its own start time and repeat pattern.
The RoadSync applications, which also come preinstalled use the Microsoft Exchange ActiveSync protocol to provide push synchronization of your corporate email, contacts and calendar.
Finally comes the YouTube app which, as we said, partially compensates for the web browser's lack of Flash support. Its interface is simple enough to let you find whatever you're looking for as quickly as possible.
It comes as no surprise that with the X10 mini you have Google Maps out of the box. Multi-touch doesn't work and double tapping won't do either. To zoom in and out you use the two virtual buttons at the bottom of the screen. These are hidden when not in use and only appear when you touch the screen.
A tap-and-hold on the screen activates Street view. As usual, you can enjoy the 3D view of the area, which is controlled by sweep gestures with impressive fluidity. They can also make use of the built-in compass for an even better experience – just hold the phone in your hand and turn around and Street view will follow you.
Voice-guided turn-by-turn navigation isn't available on the X10 mini’s Google Maps. Still, there is some kind of navigation: your route and current location appear on the screen so you'll be able to reach your goal, assuming you can read maps of course.
However, the other preinstalled map application is Wisepilot to pick up where Google Maps left. The thing about Wisepilot is that it requires a license for voice guided navigation and it downloads data over the Internet. That makes it unsuitable (or at least really expensive) for using abroad.
There are already several ways around that of course. The Android Market offers a dozen of applications so it’s up to you to pick one that best suits you. The problem is that the screen and the phone itself seem too small to use for navigation but we guess everyone should judge that for themselves.
