He mentions in the video that he filed a patent for it not so long ago.

I suppose there might prove to be a few problems there that may ultimately end up delaying its release, or worse, killing it altogether.

Filing a patent != having a patent. The Sony device is clearly prior art. I had one of those Sony's, BTW.

I can't believe anyone would compare this device favorably vs. an iPad. That's willful ignorance, I guess.

I will happily compare it favorably vs the iPad for two simple reasons. 1. Better screen for what I'll be using it for and 2. more open and thus easier to make it work the way I want a tablet to work.

Will it outsell the iPad? No. To want this device more than an iPad? Very much so.
