The last time the upcoming Sony X1000 Series Walkman (NWZ-X1050 and NWZ-X1060) showed its OLED touchscreen to the world, it was under glass at CES 2009. The WiFi-equipped player was always known to have direct access to YouTube and the internet, but exactly which browser would allow us to surf the web on a 3-inch WQVGA (432 x 240) display was anybody's guess.
Given Sony's history with using the NetFront browser on the mylo 2 internet device, however, it should come as no surprise that the official X1050 and X1060 product pages now up for perusal at the Sony Style Hong Kong website reveal that WEP/WPA/WPA2-secured browsing will be handled by the "NetFront Browser for Walkman."
There's no mention of Flash (the mylo 2 supports Flash Lite 3), but browsing should be decent considering that the full list of specs includes a line about a "podcast direct download" application and NetFront has never been a slouch. It also probably wouldn't be a stretch to assume that some touch gestures will be involved to improve the surfing experience on that low screen resolution. Tap to zoom, perhaps?
