The Acer Liquid Mini has a 3G connection with HSDPA offering 7.2Mbps downloads. Add that to the Wi-Fi that supports 802.11 b and g connections, and you shouldn't have any trouble accessing the internet.
As usual, the web browser offers full page views of sites, though the 3.2-inch 480 x 320-pixel (HVGA) screen is obviously a bit limited in terms of how much detail it shows, and if you look at a fullscreen page you probably won't be able to read much.
The browser sports a familiar double-tap to zoom feature, and if you zoom into pages there's good text reflowing so that you don't have to pan around too much to read text.
The browser supports multiple windows and opening a new one is as easy as hitting the menu button and choosing 'New window'. Bookmarks are similarly easy to use. Each one is saved as a tiny thumbnail, and you can add one by tapping an icon on the main viewing page.
Drop into bookmarks view and as well as seeing bookmarks themselves you can see a list of your most visited websites and your browsing history.
Unfortunately for fans of embedded video, the Acer Liquid Mini has dodgy Flash support. We weren't able to stream video from the BBC website, for example. But at least there is a YouTube client and that worked fine.
