Besides the super impressive XPS 13 Ultrabook announced today at CES, Dell also is refreshing their XPS 15. The XPS 15 is my primary laptop that I reviewed a few months ago and it is still one of the best on the market.
The 2015 version steps things up by replacing the QHD+ touchscreen with an ultra-high 4K resolution (3840 x 2160) display. Unfortunately, that is really about all that is new.
