Hitachi's fuel cell PDA

We were all jazzed up about the prospect of Hitachi's fuel-cell-powered PDA. That is, until we saw this photo of it posted up at I4U. They say it's just a prototype, and all we have to say is that it really better just be a prototype. If the actual final product, which isn't due out until next year,
is as grossly oversized as the PDA pictured, Hitachi is going to have a hard time convincing anyone to buy one.
