After updating models like the Xperia X10 and Vivaz, Sony Ericsson has  turned its attention to remodelling its Walkman range of handsets, and the Spiro is the first of such models.

The impressive looking Spiro is a slider style handset. It weighs a mere 90 grams and has compact measurements of 92x48x17 mm which means it will sit comfortably in the palm of your hand. Its curved edges just make it a lot more attractive. The Spiro features a 2.2″ screen and is capable of displaying up to 256,000 colors.

Sony is celebrating the forthcoming release of the Metal Gear Solid game on PSP with the release of a limited edition water resistant Walkman W252. It is a uniquely styled MP3 player and comes with a distinctive green camouflage finish.

The wire free Walkman, which can store up to 2GB comes with the 13.5mm EX Series headphones, which are also camouflaged. The wearable MP3 can store around 470 tunes and comes pre-loaded with six music tracks from the game.

A quick three-minute charge is sufficient for 90 minutes listening time. The battery on full charge provides 11 whole hours of listening time.

Sony now has a great product to offer to all fitness enthusiasts. The new NWZ-W252 W -Series Walkman MP3 Player. It is wireless, lightweight and housed in a water resistant frame to facilitate extended use for both indoor and outdoor usage. It doesn’t really matter any more if it’s raining.

Also, you can now transfer all your music files and playlists straight from your PC or the iTunes library. It has a maximum capacity of 2 GB and can hold about 500 songs, each about 4 minutes in length. There is also a quick charge function that lets you charge the player in just 3 minutes for a good 90 minute usage. When charged fully its battery can power 11 hours of non-stop music!

On Wednesday Sony celebrated 30 years of the Walkman, as did many consumers. First released in 1979, the tape playing music player cost £120 in the UK and originally named Stowaway. In Australia it was known as FreeStyle and as Soundabout in the US. Japan had the name of Walkman which caught on around the world and become the known name for the device. Within the first two months 30,000 were sold and over a decade 50 million were purchased.

After the recent announcement from Sony Ericsson about the Idou, Ubergizmo – who shared the news -  have had a chance to snap some photos of the upcoming device.

The Idou, as it’s currently called, may when it’s released go by a different name according to the screenshots. Further information about the Idou has also been released, including information about the shipping date. It is expected to be released within the second half of 2009. As well as it’s impressive screen size, it’s also confirmed that the screen is actually a touch screen, allowing ease of use when it comes to the multimedia features.
