Update: Amazon UK has these babies for £87.99. That is a huge bargain and it is criminal not to take advantage of the deal/pricing mistake. The orange/silver version is also going for £87.99, though the red version is curiously priced at £99.99. Note that Amazon UK does not ship electronic products overseas, though Advanced MP3 Player does (with minus VAT ye lucky buggers).
Sony's latest Walkman, the S63x series has received critical acclaim from various tech pundits due to its ability to offer superior sound quality. Like previous Walkmans, the S639 is a no-fuss gadget whose primary function is to deliver great sound quality. According to some Head-Fi posters, the SQ is even better than Sony's classic A818. If you are a UK resident and a valid license fee player ;), you will be glad to find that the S639 is also compatible with BBC's iPlayer allowing you to catch up with the latest episodes of Top Gear and Strictly Come Dancing.
Now, thanks to the current economic climate, the S639F 16GB model is on sale for £99 and is available in black, red or silver. That is a great value for money.
