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: 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.
Summary: I purchased a refurbished 14Z because it seemed to have the features I required at a reasonable price. However, I need a system with Windows 8 Pro. If you select the "View Details" link from the 14Z listing on the Dell Outlet refurbished Inspiron 14Z page, it clearly lists Windows 8 Pro as a feature of the 14Z. I purchased based on this.
