AnandTech has taken a look at three Intel CULV based laptops, the Acer Aspire Timeline AS1810T, Dell Inspiron 11z, and Gateway EC5409u. You can check it out over here.
These laptops are representative of what you'll find with most other CULV offerings, but you can still decide between a larger or smaller chassis and some other items. Some of the differences are easy to analyze even without using a laptop in person: a larger chassis will weigh slightly more and you might get an optical drive, or you might find a few select companies offering a higher resolution LCD. What we can't say is whether these other laptops have better LCDs or not (most likely not, though the higher resolution would still be a benefit), how the keyboard and touchpad feel, or if there are other useful features that aren't immediately visible. Ultimately, price is often the biggest factor, with entry-level CULV designs starting at around $400 (if you can find them in stock) and most ranging up to $650. Beyond that, there are designer CULV laptops and business tablets that can push pricing into the $1500+ range, but we aren't looking at that category in this roundup.
