Actually my notebook (from where I am posting) displays quite nicely at 1920 X 1080 in a window to the right of a MS Access application I am building. Television is another story and not really a good comparison with a computer. Most of us use them for two very different things. Most people don't watch TV on their computers. My computer is a work tool, not a box to play games on or chat with a 100 friends. If I can keep multiple windows open with applications concurrently it is a definite advantage as I am often sharing information between them.
Notebooks were never designed with the intention to be "small" - only portable. I have a desktop in my office with more capacity, memory and features. My notebook allows me to sit out here on my deck and work, enjoying the sound and view of the Pacific ocean surf below me with my feet up and sipping coffee with two shots of Irish Creme. If the size of this thing ever exceeds the size of my lap we'll talk.
Life is good and I love the wide screen format on my notebook.
