I need a fast desktop replacement notebook computer to use in my home office. My preferences would be a Windows 8 machine with a i5 or i7 fourth generation processor. A good backlighted keyboard with numeric keypad. At least a 1600X900 or better screen. Even if it is not going to get out of the office I would like it to be solid and quality build. Which are the best makes? There are so many makes today. I looked around a little. I didn't like HP's keyboards. Thickness and weight is not important I think of Lenovo, Dell's new 7000 series, Sony Vaio or Toshiba with 17" display. What do you thing? Thanks.
