People tend to either love or hate Sony Ericsson phones. I’m not a fan personally, but Lucy over at our sister site ShinyShiny loves them. My main objection is the software, but that bugbear is about to be stripped away by the announcement that SE will be developing an Android phone.
Having only just joined the Open Handset Alliance, Sony Ericsson won’t be dumping Symbian and Windows Mobile, but claim that Android will “complement” the operating systems that they currently use. Still, whatever you think of Sony Ericsson, more open-source handsets is a great thing.
