OMG I've been waiting for OLED to mature since - IDK - forever?!?
Honestly, there's no electronics show anywhere without some booth preaching the advent and greatness of OLED...
Personally, I would welcome the screens with open arms. Lately I've been using both my PDA and my notebook quite a lot and I love the things a notebook allow me to do while on the move, but I hate it's bulkiness when compared to my PDA... I think I know why they don't call them laptops anymore: you can NEVER use them on your lap: you need a table and a chair, and both you hands...
Then again, My PDA may be a lot more mobile, playing through media like nobody's business, handling communications and GPS, fitting nicely in my pocket, but it's so damn small for web surfing, text and the like. Now, don't get me wrong, I've read all 7 Harry Potter volumes on it (yes, go ahead, laugh...) without issue and I do have my CISCO portable command guide on it as well, but... something's still lacking...
I think OLED is about to make a true convergence possible. With screens taking up less space and energy, the laptop from the picture above could do away with the keyboard altogether, and be a practical tablet. Maybe a foldable keyboard and USB expansion capability can do away with the need of a hard keyboard altogether. Personally, I don't need a keyboard all that much when I'm on the go and a virtual one, on a touch screen, would do just fine for me. When I'm at home or at the office, I use, my desktop anyway - for anything requiring serious work.
Just my thoughts...
