Tabs definitely seem interesting. Plastic Logic showed something that looked like tabs on their device which seemed pretty cool to jump through various docs. I'd be interested in seeing how its incorporated. If you could have a PDF and a notepad open at the same time and switch back and forth between them in tabs that might be pretty interesting. Glad to see they are producing updates for this device and expanding the current capabilities rather than just abandoning it and coming out with a new device. A for effort for Irex
