Almost as if on cue, just after we complained about robots of dubious value, we find two toys that we especially like. First was the iPod Transformer. (OK, so it's not a real robot, but we still want one.) Second is the "Plen," a Japanese invention that can actually skate around your desk and even do skateboard tricks on any flat surface, according to Popgadget. And before you choke on the price--$2,000--be sure to check out the YouTube clip. You might just change your mind.
