Two months back, the buzz was about Sony’s Rolly, a device that operates like a MP3 player and shakes to the beat on its two wheels. Tough it hasn’t reached the North American market, but to my non-surprise it is performing well and in fact has won the heart of the geeks residing in Japan. Considering its performance chart moving northwards, Sony is undulating a special edition Christmas themed Rolly that comes preloaded with Japanese adaptation of rhymes like Santa Claus is Coming to Town and White Christmas. But to be the proud owner of this Christmas Rolly, you need to be a Japanese national and heart to drop $380 to pick this dancing queen. For shipping, 19 December is been scheduled. Considering this, it can be calculated that it will reach your home on the big day itself.
