Can't decide whether to buy a new touchscreen phone or a new media player? Sony Ericsson has both covered in a single unit, courtesy of the newly-launched Yendo Walkman phone.It's the first full touch Walkman phone, using the four corner touch UI from the Sony Ericsson Xperia family and the familiar Walkman experience for a device that's certain to appeal to music fans who want the look of a high-end phone, but don't want the price tag. Sony Ericsson has yet to release details of that price, but scanning through the remaining features, we don't believe this is a top-end handset for a minute.But before that, let's look at the Walkman end of the phone. It offers Touch TrackID, MediaGo and PlayNow functionality for easy access to and indentification of your tunes, while a 3.5mm jack gives you options when it comes to buying a decent set of headphones (that's if the ones included don't cut it for you). There's also an FM radio if you need one too.Outside of the Walkman, there's that 2.6-inch touchscreen, which should be good for viewing Facebook and Twitter updates (apps are included for both) and accessing the web via Google from the standby screen. A 2-megapixel camera with 4x digital zoom is unlikely to excite, but the option of a wide range of colours just might if colour is your thing.Aside from that, this is average mobile phone by numbers, with all the basics you would expect from a low-to-mid-range smartphone, no 3G or Wi-Fi for example. After all, the Walkman is selling this rather than the phone side.The Sony Ericsson Yendo will be available in late 2010 in 10 colours, check nearer the launch date for a price or contract details.
