Asus' Z801 Karaoke phone could be the coolest phone we've ever seen. Not for the looks, the design, the amount of megapixels, or even a fast data connection, but for its Karaoke feature. When you play back an MP3 on the Z801, you can sing along and the phone will speech-to-text what you say and display the words right on the phone.

If this feature indeed works the way they describe, this could be the best phone ever. If not, it's just another phone with a 2-megapixel camera that's available only in China. – Jason Chen
