At first glance, the Inspiron Mini 9, Dell's entry into the mini-notebook category, looks like what you might get if you left a notebook from Dell's full-size Studio line of laptops in the dryer too long. But the sub-US$500 Mini 9 carries a 1.6-GHz Intel Atom CPU, 1GB of RAM, and a solid-state drive, making it a good starter machine for basic computing at a reasonable price.

Our test configuration, priced at $474, included Windows XP Home and an 8GB solid-state drive; a 4GB version of the Mini 9 ships with Linux Ubuntu 8.04. The 8GB drive doesn't leave you much open space once the operating system and the preinstalled software (which includes Microsoft Works) are accommodated. For $40 more, you can upgrade to a 16GB drive, but then you've crossed the magic $500 threshold. One feature that is missing here--but is present in the Acer Aspire One--is an additional SD slot to allow users to insert a second SD Card, format it, and use it as another hard disk.

Working without two SD Card slots, we found that our WorldBench 6 test suite required more space than the Inspiron Mini 9's drive could spare. Since we couldn't run our benchmark tests on the Mini 9, we can't directly compare its performance with that of competing mini-notebooks like the MSI Wind NB U100. We do know that the Mini 9 loads Windows in about 30 seconds and fires up Microsoft Works in 8 seconds. Also, it can copy more than an album's worth of music (77MB) in about 7 seconds. In short, it falls in line with what we've seen from other mini-notebooks packing an Atom processor, 1GB of RAM, and Windows. We'll update this review when we obtain more-precise performance results.

The Mini 9 performed well in our battery life tests. Its four-cell battery ran for about 3 hours, 34 minutes--far better the three-cell battery of the MSI Wind, which lasted just 2 hours, 24 minutes.

As its name suggests, the Inspiron Mini 9 is tiny. It measures 1.07 by 9.13 by 6.77 inches--barely enough room to accommodate the 8.9-inch screen--and weighs about 2.28 pounds.

The glossy 1024-by-600-resolution display looks reasonably sharp and reproduces color extremely well. Unfortunately, if you don't view it from precisely the right angle, the screen looks a little dim. You can adjust the angle, but you may still find yourself contorting into ergonomic stress positions in order to get an optimal view.
