Compared to other screens I have seen in this size the Z blows the competition out of the water.

Clicking on a tile opens a small shelf that displays all your content for the category.

Operations is quiet, the high-resolution LED-backed screen is superb - but you need to have good eyes, I can imagine others will have a hard time with the super-fine resolution.

It ran our Street Fighter IV test at native 1,366x768-pixel resolution at 44.7 frames per second, which is decent.

Our $1,999 unit came fully equipped with Intel’s latest 2.4-GHz Core 2 Duo P8600 processor, 2GB of DDR3 RAM, and a 250GB hard drive.

The $1,599 model features a 2.8-GHz Intel Core i7 2640M CPU, 8GB of RAM, and a 256GB SSD with Nvidia switchable graphics.

It's just to much chip to allow for cooling, so the dual core i7 is mainstream, but if you look close, this one has a much faster i7 than many.

One of the things we love most about Dell is its flexible configurations, and though this is more limited on the Z range, you should still see a processor choice of dual-core Intel ‘Sandy Bridge’ Core i5 to i7, 6 - 8GB of RAM, a 500 – 750GB hard drive running at a speedy 7,200rpm and, on the more expensive models at least, a dedicated Nvidia GeForce GT 520M graphics card.

This review is for the VPCZ line, and the version I have has the Core i7 M640, and 8 GB RAM.

6GB of RAM is pretty generous compared to the 4GB you usually get on budget systems, and should be enough for pretty much anything you’d care to throw at it.
