The Acer Liquid is surprisingly devoid of native applications when you turn the phone on for the first time (compared to its peers), with only RoadSync catching the eye thanks to the way it extends the Liquid's functionality so much through corporate connectivity.
Google Talk is also included as part of the Android firmware, and offers a simple way to communicate with your buddies over the chat service. You can switch between windows of friends relatively easily, but there's no ability to add the video chat functionality from this service over the internet.
Acer has added Spinlets to the Liquid as well, which initially seemed pretty cool - music from albums that you could stream for free from your device. However, the range is limited to around 10 albums, and we only recognised music from The Killers - hardly the Spotify slayer we were hoping for.
File viewer Documents To Go also gives the Liquid another business edge, with the ability to view Microsoft Word, Excel and PowerPoint presentations. Datawiz has been sneaky in putting this onto the Liquid S100, as you can't edit docs on the go until you buy the full version.
And, of course, there's Google Maps, which is complete with StreetView as well. This works very well on the Acer Liquid, with pictures loading up fast when you move into the map to scope out an area before you get there, and navigating across vast terrain in the 2D mode also rendering quickly.
When thinking about applications on the Acer Liquid, we do think it's important you download a third-party application manager from the Market, as this will help conserve the battery life (which is crucial, as you will see later on in this review). There are a few good free ones, so just try them out and see which takes your fancy.
Given the expanding nature of the Android Market app store, we're not sure this and future Android phones will need a vast amount of inbuilt applications to be rendered a decent device - the core things from Google are there and for us that's all we really want out the box.
