Photos from CES Unveiled: Vegas' opening night

It seems like only five days since digital music Craver Nate was demanding a 'save for later' feature in iTunes. Oh wait -- it was. Fortunately, the likes of Polk have thought outside the box with an Innovations Award Honoree called the I-Sonic ES2, an iPod dock and so-called 'HD Radio'. When the I-Sonic ES2 plays a song you like, you just hit the big blue Tag button. Your docked iPod remembers the tagging details so when you next plug your scroll-wheeled wonder into your computer, iTunes launches with those pesky tunes you just can't get out of your head front and centre.

Sounds great for this song we heard the other day, it goes, "Never Gonna Give You Up, something something something..." If only we knew what it was called!
