Summary: I first ordered this laptop because the ad description said it was a core I5 with Windows 7. Simple huh? When it arrived it turned out it was a Core I3 with windows 8, I sent it back and reordered from another vendor this one came with Core I7 and windows 8 it also has touch screen and a backlit keyboard and the case is brushed aluminum with a bright finish. So this time I got much more than I bargained for, in a good way.
Summary: I had owned three Dell laptops and two desktops before purchasing this one, and was hoping for the good performance and quality I had come to expect from Dell, but I have to say I was bitterly disappointed. I think a lot of the performance suffered in Dell's efforts to cram the computer into that beautiful thin design as they rushed the release of this "ultrabook" without it being quite ready.
Summary: This laptop is beautifully constructed. Lightweight, easy to type on, and peppy touchpad. I purchased this particular "ultrabook" because it has a DVD drive but still weighs in at about 4lbs. Battery life seems to be acceptable (I get about 4 hours unplugged watching TV/movies). I do think it's a lot of bang for your bock for ~$500. That said, there are a few things that would benefit the 14z (5423). First is a backlit keyboard.
Summary: I would give 5 stars if this computer came with Windows 7. I thought that was what I was getting. Too bad for me. The good: the keys are spaced well to minimize typos, it is extremely lightweight, everything mechanical seems to work well. The 2-toned brushed metallic surface is sleek and classy, if you are interested in pure style. The bad: the 3rd time I turned it on, it did not boot past the Dell logo. It took 1 hour and 27 minutes on the telephone to get it working.
